We outline some of the issues that need to be taken into consideration in upcoming studies on model-based decision support in service networks and manufacturing. Integration problems that look at how independent the decision-making entities are when there is an imbalance of information, decision-maker preference modeling, finding robust solutions (solutions that don't change when the problem data changes), and shortening the time it takes to make and use models are all covered. The process of solving a problem involves analyzing the problem, designing suitable algorithms, and evaluating how well those algorithms work. We are interested in a field test using the expanded application systems after a prototype integration of the suggested ways within application systems. We contend that the proposed research agenda necessitates the interdisciplinary cooperation of researchers in business and information systems engineering with associates in computer science, management science, and operations research. We also provide a few representative examples of pertinent research findings.
