I. INTRODUCTION

I.1 The Decision EnvironmentDSS for Notebook Selection has been aimed at understanding the importance of the requirement of a trustworthy decision support system in making decision to buy a notebook for consumers.

The purpose of this project is to provide an environment in which consumer preferences are transmitted to the system and the system returns the best alternative notebook for the consumer. Primarily our system concentrates on finding the best notebook that has closest specifications to consumer preferences and is most economic.

Preferences of consumer, their priorities and the major quantitative specifications of notebook create the decision environment. Consumer is the main decision maker in our system to buy notebook. Consumer demand is the main factor that determines the decision period. Urgency of the demand mainly shapes the decision period.

The complexity of decision environment results from;

High number of notebook models.

Reliability of the price. (Price of the notebook in our system may not be always consistent with price of same product on another suppliers)

A DSS for the notebook selection process is obviously essential to have a more systematic and reliable selection environment. To make the decision, some criteria have to be satisfied. The decision of selecting the best notebook is based on;

Set of requirements that are consistent, should meet the expectation of consumer

Decision making environment should be objective and reliable

Decision environment should be user friendly.

Consumers can select notebook with the conventional technique but computerized decision support system makes the results more reliable, objective and faster. The conventional technique with computerized decision support system can also be beneficial option. The system can maximize the possibility of buying the best alternative notebook at the most economic price. Because the system provides us the most objective and affordable choices, thus consumers don’t make any unproductive decisions. Moreover the decisions are made in less time in our system, compared to conventional technique.

I.2 Mission of ProjectThe mission of this project is to find the best notebook at the most economic price and mostly close to consumer preferences. Giving the best alternative among all the options is main purpose of the project.

I.3 Scope of ProjectOur project considers both the qualitative preferences of consumer and the quantitative specifications of notebooks. These qualitative preferences include, brand, color, hardware specifications such as CPU, hard-drive capacity, RAM and video card, software such as operating system, warranty and price.

I.4 Methodology

In today’s world when consumers want to buy something such as notebook, they have too many options. Having too many options makes decision process very complex and time consuming. Moreover as stated in the paper of Columbia University Professor Sheena Iyengar, consumers given too many choices are 10 times less likely to buy.1 In the worse scenario, consumers can make a careless decision in this complex environment. DSS for Notebook Selection is the best way to solve this problem we face. We decided to use Analytic Hierarchy Process (AHP) to find the best selection. Consumers do not always choose by looking at the quantitative specifications of the products, instead they sometimes decide by looking the qualitative properties. Therefore, direct comparisons are necessary to establish measurements for intangible properties that have no scales of measurement.2 Because of the decision process includes both objective and subjective considerations; AHP would be useful to make bilateral comparisons by including weights. Choosing a notebook requires consumer to determine and evaluate a large number of criteria. In our methodology, consumer prioritizes the criteria which are required for decision making. DSS for Netbook Selection gives the final decision by firstly making the sub-criteria comparison and then comparison of sub-criteria results.

II. LITERATURE SURVEY

II.1. Website & Journal Review

What is Decision Support Systems?

Decision support systems (DSS) are computer technology solutions that can be used to support complex decision making and problem solving.3

DSS have evolved significantly since their early development in the 1970s. Over the past three decades, DSS have taken on both a narrower or broader definition, while other systems have emerged to assist specific types of decision-makers faced with specific kinds of problems. Research in this area has typically focused on how information technology can improve the efficiency with which a user makes a decision, and can improve the effectiveness of that decision.4 In our project, we created a DSS which tries to get optimal alternative according to users preferences. A DSS is required because it is a hard decision to select best laptop which meets user’s needs.There is a substantial amount of empirical evidence that human intuitive judgment and decision making can be far from optimal, and it deteriorates even further with complexity and stress. Because in many situations the quality of decisions is important, aiding the deficiencies of human judgment and decision making has been a major focus of science throughout history. Disciplines such as statistics, economics, and operations research developed various methods for making rational choices. More recently, these methods, often enhanced by a variety of techniques originating from information science, cognitive psychology, and artificial intelligence, have been implemented in the

4

form of computer programs, either as stand-alone tools or as integrated computing environments for complex decision making. Such environments are often given the common name of decision support systems (DSSs). The concept of DSS is extremely broad, and its definitions vary, depending on the author’s point of view. To avoid exclusion of any of the existing types of DSSs, we will define them roughly as interactive computer-based systems that aid users in judgment and choice activities. Decision support systems can aid human cognitive deficiencies by integrating various sources of information, providing intelligent access to relevant knowledge, and aiding the process of structuring decisions. (Druzdzel & Flynn, 2002)

Analytic Hierarchical Process

The foundation of the Analytic Hierarchy Process (AHP) is a set of axioms that carefully delimits the scope of the problem environment (Saaty 1986). It is based on the well-defined mathematical structure of consistent matrices and their associated righteigenvector's ability to generate true or approximate weights, Merkin (1979), Saaty(1980, 1994). The AHP methodology compares criteria, or alternatives with respect to acriterion, in a natural, pairwise mode. To do so, the AHP uses a fundamental scale ofabsolute numbers that has been proven in practice and validated by physical and decision problem experiments.

AHP is a method for ranking decision alternatives and selecting the best one when the decision maker has multiple criteria (Taylor, 2004). It answers the question, “Which one?” With AHP, the decision maker selects the alternative that best meets his or her decision criteria developing a numerical score to rank each decision alternative based on how well each alternative meets them.

In AHP, preferences between alternatives are determined by making pairwise comparisons. In a pairwise comparison, the decision maker examines two alternatives by considering one criterion and indicates a preference. These comparisons are made using a preference scale, which assigns numerical values to different levels of preference (Taha, 2003). The standard preference scale used for AHP is 1-9 scale which lies between “equal importances” to “extreme importance” where sometimes different evaluation scales can be used such as 1 to 5. In the pairwise comparison matrix, the value 9 indicates that one factor is extremely more important than the other, and the value 1/9 indicates that one factor is extremely less important than the other, and the value 1 indicates equal importance (Sarkis and Talluri, 2004). Therefore, if the importance of one factor with respect to a second is given, then the importance of the second factor with respect to the first is the reciprocal. Ratio scale and the use of verbal comparisons are used for weighting of quantifiable and non-quantifiable elements (Pohekar ve Ramachandran, 2004).

Since 1977, Saaty (1980) proposed AHP as a decision aid to help solve unstructured problems in economics, social and management sciences. AHP has been applied in a variety of contexts: from the simple everyday problem of selecting a school to the complex problems of designing alternative future outcomes of a developing country, evaluating political candidacy, allocating energy resources, and so on. The AHP enables the decision-makers to structure a complex problem in the form of a simple hierarchy and to evaluate a large number of quantitative and qualitative factors in a systematic manner under multiple criteria environment in confliction (Cheng, et al, 1999).

5

The application of the AHP to the complex problem usually involves four major steps (Cheng, et al, 1999):

1. Break down the complex problem into a number of small constituent elements and then structure the elements in a hierarchical form.

2. Make a series of pair wise comparisons among the elements according to a ratio scale.

3. Use the eigenvalue method to estimate the relative weights of the elements.

4. Aggregate these relative weights and synthesize them for the final measurement of given decision alternatives.

The AHP is a powerful and flexible multi-criteria decision-making tool for dealing with complex problems where both qualitative and quantitative aspects need to be considered. The AHP helps analysts to organize the critical aspects of a problem into a hierarchy rather like a family tree (Bevilacqua et al, 2004).

The essence of the process is decomposition of a complex problem into a hierarchy with goal (criterion) at the top of the hierarchy, criteria and sub-criteria at levels and sub-levels of the hierarchy, and decision alternatives at the bottom of the hierarchy. Elements at given hierarchy levels are compared in pairs to assess their relative preference with respect to each of the elements at the next higher level. The method computes and aggregates their eigenvectors until the composite final vector of weight coefficients for alternatives is obtained. The entries of final weight coefficients vector reflect the relative importance (value) of each alternative with respect to the goal stated at the top of the hierarchy (Pohekar ve Ramachandran, 2004). A decision maker may use this vector according to his particular needs and interests. To elicit pairwise comparisons performed at a given level, a matrix A is created in turn by putting the result of pairwise comparison of element i with element j into the position aji as below.

Figure 1: Pairwise comparison

6

Where

n = criteria number to be evaluated

Ci = i. criteria,

Aij = importance of i. criteria according to jth criteria

After obtaining the weight vector, it is then multiplied with the weight coefficient of the element at a higher level (that was used as criterion for pairwise comparisons). The procedure is repeated upward for each level, until the top of the hierarchy is reached (Saaty, 1994). The overall weight coefficient, with respect to the goal for each decision alternative is then obtained. The alternative with the highest weight coefficient value should be taken as the best alternative. Saaty’s AHP, is a well-known decision-making analytical tool used for modeling unstructured problems in various areas, e.g., social, economic, and management sciences (Bard and Sousk, 1990; Triantaphyllou and Mann, 1995; Wabalickis, 1988).

After obtaining the weight vector, it is then multiplied with the weight coefficient of the element at a higher level. The procedure is repeated upward for each level, until the top of the hierarchy is reached (Saaty, 1980). Then the overall weight coefficient, with respect to the goal for each decision alternative is obtained. The alternative with the highest weight coefficient value should be taken as the best alternative.

II.2 Former Studies ResearchOne common model-based approach is to model customers’ preferences using a vector of weights representing relevancies of product attributes to a given customer. Lee et al. used this approach for recommending DVDs to customers. Their agent based system used genetic algorithms to learn customers’ preferences. Similar approach was used in (Pazzani, Bilssus, 2002) where the system learned user preferences for the source of document recommendation. (Kim et al, 2002) utilized web usage mining for decision tree induction in order to generate personalized recommendations in e-shopping support. One way to elicit customer preferences is through the use of conjoint analysis: a technique long used in marketing (Louviere, 1988). In this approach customer is presented with different products and feature combinations and asked to compare them in terms of desirability.

Figure 2: Client-server system

In a previous study by Rustam Vahidov and Fei Li in 2005, fuzzy modeling was used to select the optimum notebook according to the given customer preferences. They also used constraints to get the list of feasible candidates as we are going to do. They stated the reason for choosing fuzzy modeling that they were allowing the customers to have some level of softness in expressing their preferences. Their model also reflects the degree of vagueness in customer preferences. Instead, our model chooses the optimum candidate among many, and do not reflects the customer vagueness therefore we don’t need to use fuzzy modeling; instead we decided to model our study using AHP.

III.3.3 Modeling of Selection

The criteria are determined and given relative importance for each criterion by consumer. Intensity of importance grades of pair wise matrix is ranging from 1-9. A basic assumption is that if attribute A is absolutely more important that attribute B and is rated at 9, then B must be absolutely less important than A and is valued at 1/9.

Figure 8: The Saaty Rating Scale

The next step is the calculation of a list of the relative weights, importance, or value, ofThe factors, such as price and CPU (technically, this list is called an eigenvector).

Value of Consistency Ratio (CR) is important to judgment. If the CR is much in excess of 0.1 the judgments are untrustworthy because they are too close for comfort to randomness and the exercise is valueless or must be repeated.

Figure 9: Values of Consistency Ratio

First row shows size of matrix, second shows random consistency index.

According to our survey, price gets the highest point with 34 percent of iteration rate among other criteria, and CPU has second highest point with 24 percent. Brand, Ram and Video Card have same rate with 10 percent. Design and Screen Size have 6 percent of iteration rate.

III.3.4 Data Collection

To determine criteria which we used to evaluate for selecting notebooks, we got information from sales representatives in computer stores about determinants of notebook selection of costumer. Moreover, we created a survey about notebook preferences of users. According to information we collected from sales representatives and the survey, most important factors of selection a notebook are performance, design, brand image, graphics and other features such as warranty and battery life. In our survey, we selected the highest five main criteria which had highest points and fourteen sub criteria. To get quantitative information about CPU, RAM, HDD, Screen Resolution and Video card performances, we created a database and use these data in alternative comparisons. Qualitative data like color and Screen Size will be obtained from user, because these preferences may change according to person. Price is not a criterion in our system but we use it while creating benefit/cost ratio which provide us an evolution about general value of the notebook considering also price. We gather price information of notebooks from some B2C companies such as Vatan Computer and Bimeks.

IV. ASSESSMENTWe decided to use Analytical Hierarchy Process as our methodology, and then we decided to make a DSS for Notebook Selection because each of us has a general knowledge about notebooks and their specifications.

Then two of us made an interview with a sales representative in a computer store and we prepared a survey. Thus we got the information to define criteria for notebook selection.

After our mid report presentation we improved our hierarchical tree based on the recommendation of our instructor Asli Sencer ERDEM.

Finally, we designed our system and started coding the system. Our time was restricted and the coding is complex and challenging. Our instructor also wanted us to make a what-if analysis, it was struggling for us because there were a little time to due date.

IV.1 Project Plan

Difficulties: Our schedules are not the same so finding a time that fits for everyone is a difficulty for us.

Meeting Place: We decided to meet at South campus study hall, but we are going to use the Library in North campus for the literature review. We also created a Google group (MIS463_DSSNotebook) for the project, so we are going to contact each other through this group and share documents and information related with the project.

Meeting Time: We decided to meet according to the schedules of the team members.

Coordinator: The team decided to work collaboratively, each group member attend the meetings and contribute to the project. By this way, we can make brainstorming and realize possible errors or deficiencies.

Generally, to improve system better, all functions of the project were tested according to scalability, maintainability, usability, performance.Design of the website is user friendly and ease of use. According to Usability function of testing, our system is well designed and easy to understand. User can filter the computers according to many categories such as price, brand, CPU and etc. All pc has an image to identify their appearances. There is a check box under each computer it makes easy to select alternative computers for comparison. After user clicks the comparison button, criteria page opens. Comparison criteria are grouped under more general main criteria and there is an explanation area which explains how to make a comparison. After selection of criteria, product comparison page opens. There is a slider for each pair wise comparison which makes the usability easier and there is also explanation about the comparison. At the result page, computers are ordered according to benefit/cost ratio. User also can change the weights of selected criteria by using sliders and clicks on recalculate button. Each page has a back button to make it easy to shift between pages.Admin of the system can add, edit or delete the parts, new computer, new brands and new criteria. Therefore, our system is said to be flexible and our system suits the maintainability criteria of testing.

44

Because of our database provider, which is MS Access, there may be a problem on our website when there are many users at the same time. MS Access doesn’t provide its service for many users simultaneously. Thus, it can be said that scalability of the system is not perfect.General performance of the system is very high according to time and resources used. The system shows results successfully in short time and it works on different browsers properly.

VI. CONCLUSIONUp to now, we have completed the all steps that are promised within the planned

intervals in the master plan. In the literature review, we have searched about the processes affected the decision process of selecting notebooks. Moreover, we looked for the AHP processes and applications to develop a model for our project. Then, we created a survey to eliminate criteria for notebook selection and polled the necessary information to understand the preferences and priorities of notebook customers. We also made interview with a computer vendor about the quantity of sales and what are the most important criteria determined according to sales. Then we analyzed all collected data from literature review, survey and interview and develop our model with AHP. We determined our criteria after the survey and composed a hierarchical tree. Then, we made a general pair wise comparison and a specific pair wise comparison for each criterion in terms of brand names. After all steps are completed for the model, we prepared our mid-report which include all processes of our work; literature view, developing model, and necessary diagrams. Consequently, we prepared for the presentation.

Generally, we corresponded with our master plan and achieved to complete all processes on time. Our literature review took less time than we assumed and so we started our next processes earlier than we planned. Therefore we focused on mostly developing the model. Our new master plan can be found above which included all processes done and the upcoming processes. Next processes include the processes of data collection and organization of this data, coding interfaces and validation of the system. We will proceed the next phases according our task allocation and master plan. Every group member will do the phase that is assigned to him/her and will complete them until the date that is determined in master plan.

We completed: Literature review of the project (Former studies, survey, web) Developing the model Mid report Application of the model Website Final report

Firstly, we changed the midreport after the presentation according to the instructor comments. Then we created a website and applied the methodology and model to this website after the mid-report. We prepared a system that works automatically to find the most suitable notebook for customer according to AHP model. The AHP model is determined by customer preferences. Customer filters the alternatives and select at least 3 and at most 7 notebook. Before calculation, user selects the criteria and compares them with pair wise comparison. If she wants, she can change the weight with the “what if analysis” which appear on results page. At the last step of the project, we tested the system. At the end, we prepared our final report and presentation.
