tailieunhanh - Lecture Advances in supply chain management - Chapter 29

When you have completed this chapter, you will be able to: Explain the importance of work design, compare and contrast the two basic approaches to job design, discuss the advantages and disadvantages of standardization,. | PART IV ARCHITECTURE OF SELECTED APS SUMMARY of Last Lecture The APS implementation resulted in major improvements of the planning and logistics processes and helped to improve major KPIs. Table lists the improvement of logistical KPIs from 1999 to 2002 and the target value. The improvement of the customer service level and the delivery reliability resulted in additional revenue. Better forecast accuracy helped to reduce the inventory levels and by that reduced the direct material costs by approx. –2%. Through better planning support the inbound logistics costs and the process costs in purchasing and planning departments could be decreased. In addition to these business improvements the following “Lessons Learned” can be summarized from the project work: • The batch interfaces between i2 and SAP R/3 were easier to implement and to manage than expected. For example the adaption of the interface programs from SAP R/3 f to c was accomplished within 6 weeks without support by external consultants. • The online integration between i2 Demand Fulfillment and SAP R/3 SD turned out to be rather difficult to implement and stabilize. Especially the consideration of the SD order types and the specific customizing of SD was a source of many issues. DETAILED COMPUTER ASSEMBLY SUPPLY CHAIN COMPUTER ASSEMBLY PROCESS The computer assembly process is divided into two main parts • The assembly operations • The testing and packing operations. The first step is the assembly of the system board. Boards are assembled in batches of 100–1,000 pieces. The board assembly lead-time for one batch is roughly half a day. There are approximately 20 different system boards for PCs and another 20 for servers. The system boards for notebooks are procured. The second step is the configuration of the board. In this step, the processor assembly—consisting of the processor and the cooling—and the memory are put onto the board. Cont’d . The third step is the kitting . | PART IV ARCHITECTURE OF SELECTED APS SUMMARY of Last Lecture The APS implementation resulted in major improvements of the planning and logistics processes and helped to improve major KPIs.
