Multi-Objective Integrated Production Planning Model and Simulation Constrained Doubly by Resources and Materials

Abstract

Based on analysing the defects of ERP planning system and researching related literatures, a multiobjective integrated production planning model is constructed which is constrained doubly by resources and materials. The model takes delivery on-time, reduces inventory, reduces overtime work, maintains safety inventory as its optimization objectives, and can achieve the integrated optimization of production planning, material requirements planning, resource requirements planning, inventory planning and overtime work planning. We build a mixed integer programming model and use Lingo to complete the model solution and simulation analysis, the case shows that the optimization method provided by the model has strong feasibility and effectiveness.

Using CAD and Flow Simulation for Educational Platform Design and Optimization

“…Flow concentrators also generate under utilization of the structural elements of the manufacturing system leading to financial loss [9].…”

Simulation for Improving the Performance of Small and Medium Sized Enterprises

“…By performing simulations under different conditions (changing model parameters) performance measures of simulated processes can be monitored depending on the model parameters' value. The following performances of the process are chosen to be followed: delivery performance, capacity utilization and inventory turnover (Table I, II and III) [2,6,[20][21][22].…”

“…For these very reasons, manufacturing enterprises often use ERP (Enterprise Resource Planning) system to schedule and manage resources uniformly in order to enhance competitive advantage, efficiency and performance of business process. Usually the planning systems of ERP lack an integrated overall optimization mechanism, so the production planning, the material requirements planning, the capacity requirements planning and other plans of the planning system need to be calculated separately, and the coordination of multi-level plans is completed manually [6]. However synergistic effect of a whole depends heavily on the chosen strategy and managerial decisions made by the managers at the operational level during adjustment of work processes.…”

“…Due to this, there was the need for development of new tools that could be used to support decisions in daily production planning and inventory management [2][3][4][5][6]. The operative production planning becomes a complex process closely associated with variations in the parameters of the preparation and production.…”

“…Based on this, some researches propose integrated production planning models as methods to solve the problem of simultaneous optimization of different plans in enterprises. The paper [6] proposes a multi-objective optimization model of integrated production planning. Production plan under this model, besides materials and production capacity, also considers performance objectives of manufacturing process.…”
