Supply chain management (SCM) is critical to the success of manufacturing industries. Advanced production planning and scheduling functions capable of coping with activities in a supply chain (SC) are presently needed. A finite capacity material requirement planning (FCMRP) system for a three-stage SC, defined as “3-SC FCMRP,” is presented herein....

Context 1
... the proposed 3-SC FCMRP system is developed as the heuristic-based LP model. The 3-SC FCMRP system design comprises six modules, as shown in Figure 2. All input data of the 3-SC FCMRP system is organized in a form that is easy to be understood and used by every module, called an "integrated network of operations" (Figure 3). ...
Context 2
... 1: Set-up an integrated network of operations. This module constructs an integrated network of operations of a 3-stage SC from the input data, as shown in Figure 3, to allow planners to understand the FCMRP problem at a glance. It clearly shows all manufacturing operations (both fabrication and assembly) at the main manufacturer, customer C1, and supplier S as rectangular blocks. ...
Context 3
... orders and the integrated network of operations ( Figure 3) are used as inputs for Module 2. The outputs of the VMRP system are the production plans for the different factories and the purchasing plans for the different types of suppliers, as shown in Figure 4. The purchasing plan of parts to be purchased from supplier S2 is released to the supplier. ...
Context 4
... Module 6 uses an LP model to determine the optimal start times of all operations to reduce the total cost of the entire SC system. Based on the integrated network of operations presented in Figure 3, the indices, sets, parameters, and the decision variable are defined as shown in the notation list (see Table 4). ...
Context 5
... parent operations must be started after their child operations have been finished. Based on the integrated network of operations in Figure 3, the precedence relationships are divided into two cases. ...
Context 6
... demonstrate the feasibility of the proposed 3-SC FCMRP system, the authors applied it in an experimental case. Details of all operations required to produce six products, and the first-and secondpriority work centers of each operation are summarized in the integrated network of operations, as indicated in Figure 3. Note that it is the same as the illustrative example in the previous section. ...

... Figures 13 a and b present the plot of the significant interactions (D×A and D×S) from Table 6 to identify the relationships between the subsystems. Figure 13a demonstrates the D×A interaction. The graphs are separated into two groups; graphs of the job-based dispatching rules are in the upper part of the figure, while those of the operation-based rules are in the lower part. ...
Context 8
... with the operation-based rules and Method 2, the average total costs are lower than the other combinations in the D×A interaction. Figure 13b demonstrates the D×S interaction. As with Figure 13a, graphs of job-based and operation-based rules are in different groups. ...
Context 9
... 13b demonstrates the D×S interaction. As with Figure 13a, graphs of job-based and operation-based rules are in different groups. The interaction between the operation-based rules and shifting options has a lesser effect on the average total costs than that between the job-based rules and shifting options. ...
