s information technology provides industry with the means to identify new product and service opportunities, the increasing demand for these products and services places new demands on information technology. This cycle has created unprecedented requirements for integrated enterprise systems and applications, which are capable of modeling rapid changes in business policies, workflow and information processing. A new breed of systems we refer to as object-oriented enterprise frameworks (OOEFs) has emerged to address these requirements. Our research has studied the trends in OOEFs [5, 6], the guidelines for developing OOEFs, and the economic benefits of enterprise frameworks [7]. OOEFs are designed to reduce the complexity and cost of enterprise systems, and therefore have become strategic assets for organizations across all business sectors. Evidence of this is reflected in the recent entry of flexible and extensible products for enterprise resource planning (ERP), manufacturing execution systems (MES), product data management (PDM), customer service/sales order processing, and other commercially available, framework-based applications. While the Object Management Group’s (OMG) Web site identifies several successes in missioncritical enterprise applications leveraging CORBA, it is not our intent to take a position in the CORBA versus DCOM debate—as we will see, interoperability is only one of many characteristics of an OOEF. Rather, we hope to discuss the pragmatic issues that face decision-makers, and to establish a formal set of criteria to be used in building or selecting an enterprise framework. Framework requirements are generally defined by an independent standards body (CORBA is one example), a Software Vendor (Microsoft’s MFC, COM and DCOM, FASTech’s FACTORYworks, IBM’s San Francisco Project, Philips’ New York Project) or a Systems Engineering Group (Motorola’s CIM Baseline). Frameworks combine the best features of state-of-the-art programming languages, development environments, and tools. In addition, frameworks provide an extensive library of business objects supporting the intended application domain. At one time or other, every developer or development team has created a framework. Such frameworks often Enterprise Frameworks Characteristics, Criteria, and Challenges

An Economic Production Quantity Model for Defective Items with Sales Return Service, Scrap Items and Rework
In this model, we establish an inventory model to determine the optimal inventory replenishment scheme for the economic production quantity (EPQ) model for imperfect, deteriorating items with sales return service under multiple production and rework setup. In one cycle, production process can produces the products in m production setups and reworks the defective items in one rework setup. The c...
متن کاملOptimal Batch Production for a Single Machine System with Accumulated Defectives and Random Rate of Rework
In this paper we consider an imperfect production system which produces good and defective items and assume that defective items can be reworked. Due to the nature of rework process we do not restrict the rework rate to be equal to normal production rate or constant and assume that it is a random variable with an arbitrary distribution function. We also assume as it is true in most real world s...
متن کاملNew Strategic and Dynamic Variation Reduction Techniques for Assembly Lines
Variation is inevitable in any process, so it has to be dealt with effectively and economically. It has been the focal point of many researchers to control, predict or reduce the variation of a product to increase its competitiveness in the current global marketplace. Reducing variation can be achieved in assembly lines strategically and dynamically. It can be reduced strategically by developin...
متن کاملAbsorbing Markov Chain Models to Determine Optimum Process Target Levels in Production Systems with Rework and Scrapping
In this paper, absorbing Markov chain models are developed to determine the optimum process mean levels for both a single-stage and a serial two-stage production system in which items are inspected for conformity with their specification limits. When the value of the quality characteristic of an item falls below a lower limit, the item is scrapped. If it falls above an upper limit, the item is ...
متن کاملOptimal Process Adjustment with Considering Variable Costs for Uni-variate and Multi-variate Production Process (RESEARCH NOTE)
This paper studies a single-stage production system, two-stage production system where specification limits are designed for inspection. When quality characteristics fall below a lower threshold or above an upper threshold, a decision is made to rework or scrap the item. The target is to determine the optimum target for a process based on rework or scrap costs. In contrast to previous studies, ...
