Production and Service Systems Design and Planning

Production and Service Systems Design and Planning

The design of production and service systems includes deciding on the product/service family to be produced, long-term demand forecasting, determining the materials, processes, and methods to be used, selecting machinery and equipment, and designing workflow, work systems, and facility layout. The planning problem involves forecasting incoming jobs or orders in an existing production or service system, prioritizing them, matching capacity with demand through capacity planning, and determining which jobs or orders will be processed, when, and in what quantities by existing production units.

Optimization

Optimization

Many real-life problems can be formulated in this way and are successfully applied in numerous fields such as production, supply chain, logistics, engineering design, and finance. It requires an interdisciplinary approach and background that integrate multiple disciplines, including mathematics, computer science, and management science. The fundamental solution techniques include mathematical modeling and heuristic methods.

Stochastic Models and Decision Analysis

Stochastic Models and Decision Analysis

It is used in modeling and solving engineering problems involving uncertainty in the production and service sectors, and it can also be applied to economic, healthcare, public administration, and business problems where similar dynamics arise. The field of decision analysis examines individuals’ behavior in single- and multi-criteria decision problems, both by developing analytical models and through behavioral analysis.

Fuzzy Logic and Soft Computing

Fuzzy Logic and Soft Computing

The difference between the Soft Computing approach and traditional computing methods is that it increases the robustness and manageability of solutions by tolerating uncertainty, partial correctness, and imprecision. Soft computing takes the operating principles of the human brain as its role model.
