Slide 3
Agenda Spreadsheets Spreadsheet applications in education
Spreadsheets in logistics management education Spreadsheet model of
inventory control Logistics problems modeled as discrete controlled
object in spreadsheet General remarks and future directions
Slide 4
Spreadsheets For tracking information, business processes and
flows in the organization For business modeling, analysis and
decision support As computing and teaching tool For
teaching-learning process improvement
Slide 5
Spreadsheets for Numerical calculations Information
visualization Reports generating User interface definition Complex
models defining Automation of activities (VBA)
Slide 6
Spreadsheets application in education Finance and accounting
Engineering studies Business management Operations research
Logistics education
Slide 7
Spreadsheets in logistics management education Integrated
spreadsheet models logistics strategies flow planning inventory
control allocation and aggregate planning network design and
planning Visual impact to the logistics problems analysis Required
flexibility Modeling approach combined with case analysis
Slide 8
Spreadsheet model of inventory control Discrete controlled
object concept for logistics problems modeling Clear separation
between: a discrete object (low of behavior, control domain) a
performance criterion method used to find an optimal solution
Slide 9
Control domain Performance criterion cost = ordering cost +
holding cost + purchase cost (min) Logistics problem modeled as
discrete controlled object Law of dynamics
Slide 10
Spreadsheet model of inventory control in the case of fixed
order replenishment cycle in the finite time horizon Logistics
problems modeled as discrete controlled object in spreadsheet
Slide 11
Interpretation of mathematical model in spreadsheet Logistics
problems modeled as discrete controlled object in spreadsheet
Slide 12
Data Table function Dynamic range that summarizes formula cells
for varying input cells Find optimal number of replenishments
Minimal value of performance criterion J Check less than T values
for the control variable u 1 Tool for students to better understand
dynamics of the inventory on the day by day basis Logistics
problems modeled as discrete controlled object in spreadsheet
Slide 13
Approach application Faculty of Organizational Sciences,
University of Belgrade, Serbia Students of the third and fourth
years of undergraduate studies Benefits focus on the individual
parts of the problem inventories behavior relationship between
input and output flows of inventories admissible solutions space
defining performance criterion different methods of optimal
solution finding
Slide 14
General remarks and future directions Students are allowed to
understand the problem develop mathematical model translate it to
spreadsheet model run simulation Future directions Integration of
spreadsheet models and heuristic methods Developing of logistics
problems models examples Library of useful templates for
students
