FAW: Coordination Issues in Manufacturing Systems Design andControl

对全球制造业竞争的广泛关注，导致越来越需要更好、更详细的协调，以改善制造业务的绩效。这项研究将通过三种不同的方式来研究这些问题。首先，这项研究将扩展一系列研究，解决单一制造设施内生产的不同阶段之间的协调问题。这一领域的研究将侧重于系统的规划和控制，这些系统的要素因采用准时制政策而减少库存而变得更加紧密地联系在一起。这些库存削减给满足生产目标和最后期限带来了巨大的挑战，特别是在制造-组装系统中。在这样的系统中，许多部件必须以精心编排的方式生产或采购，以确保部件能够以正确的比例匹配，从而实现生产目标。其次，这项研究将在最近建立供应商交货时间表和相关运输合同的基础上，调查不同制造设施之间的协调问题。一个关键因素是每个客户的订购模式如何影响供应商的生产成本，以及如何定义订购策略(在客户)，以及在适用的情况下，订单接受或交货日期设置策略(在供应商)，这对所有各方都是有利的。第三，研究将集中在传统上在工业和学术文献中分开处理的制造功能之间接口的协调问题。虽然过去的一些研究是在这些接口(例如，生产调度和运输物流之间的接口，质量控制和生产控制之间的接口)上进行的，但研究的重点将集中在业务和战术控制主题之间的接口以及涉及资本投资决策的主题之间。运营政策如何影响现有制造系统的实现能力，以及它们应该如何影响新系统的选择，目前还不是很清楚。同样，现有的或拟议的制造系统的物理特性如何影响良好、简单、操作控制的发展也不是很清楚。将开发分析模型，一些是描述性的，另一些是以优化为基础的。这些模型将考虑不同级别的信息可用性(相对于速度和细节)和实用的绩效评估方法。这也将使评估更好的信息系统和精心设计的奖励政策的价值，在这些政策中，协调对于改善制造业绩非常重要。

Widespread concern about global competition in manufacturing has led to an increasing need for better, more detailed coordination to improve the performance of manufacturing operations. The research will examine these issues in three different ways. First, the research will expand upon a line of research that addresses coordination among the various stages of production within a single manufacturing facility. Research in this area will focus on the planning and control of systems whose elements have become more tightly coupled because of inventory reductions resulting from the adoption of just-in-time policies. These inventory reductions have created significant challenges to meeting production goals and deadlines, especially in fabrication-assembly systems. In such systems, many parts must be produced or procured in a carefully orchestrated manner to ensure that the parts can be mated in the correct proportions, so that production goals are met. Second, the research will investigate coordination issues among distinct manufacturing facilities building on recent work on establishing supplier delivery schedules and related transportation contracts. A key factor is how each customer's ordering pattern affects the costs of production at the supplier, and how to define ordering policies (at the customers), and, where applicable, order acceptance or delivery date setting policies (at the suppliers) which are mutually beneficial to all parties. Third, the research will concentrate on coordination issues at the interface between manufacturing functions which traditionally have been dealt with separately, both in industry and in the academic literature. Although some of the past research lies in these interfaces (e.g., the interface between production scheduling and transportation logistics, the interface between quality control and production control), the research will focus on the interfaces between operational and tactical control topics and those dealing with capital investment decisions. It is not well understood how operational policies affect the realized capacity of existing manufacturing systems, nor how they should influence choices for new systems. Similarly, it is not well understood how the physical characteristics of existing or proposed manufacturing systems affect the development of good, simple, operational controls. Analytical models will be developed, some descriptive and others optimization-based. The models will consider different levels of information availability (relative to both speed and detail) and practical performance evaluation methods. This also will allow assessment of the value of better information systems and well-designed incentive policies where coordination is important in achieving improved manufacturing performance.
