Vehicle routing and production planning decision support systems: Designing graphical user interfaces

Abstract

Given the inherent complexity of vehicle routing and production planning decision support systems, designing user interfaces for them is challenging and can make a big difference in the usability of these systems. Many heuristic and optimization-oriented systems that have been implemented for this type of problem have failed in part due to a poor graphical user interface. This work proposes an approach that can be applied to improve the design of user interfaces for this type of system and make its implementation easier. The approach is based on tools that were adapted from the FW/SM system for Structured Modeling and commercially available tools, such as Powerbuilder and CPLEX. Two systems that were implemented using this approach, in two different firms, are presented. These systems run on standard PCs under MS Windows, follow the Windows applications design guidelines, and interact with relational database management systems
