    Advanced resource planning as decision support module to ERP.

    In this paper, we show that the planning and decision-support capabilities of the MPC (Manufacturing Planning and Control) system, which forms the core of any ERP (Enterprise Resource Planning) package, may be substantively enhanced by including a Decision Support Module (DSM) as an add-on at the midterm planning level. This DSM, called Advanced Resource Planning (ARP), serves as parameter setting process as well as tool for improving the structure of the ERP system itself. The ultimate goal of the DSM is to yield realistic information both for scheduling, sales and marketing, strategic and operational decision making and suppliers and customers.

    From supply chains to demand networks. Agents in retailing: the electrical bazaar

    Get PDF
    A paradigm shift is taking place in logistics. The focus is changing from operational effectiveness to adaptation. Supply Chains will develop into networks that will adapt to consumer demand in almost real time. Time to market, capacity of adaptation and enrichment of customer experience seem to be the key elements of this new paradigm. In this environment emerging technologies like RFID (Radio Frequency ID), Intelligent Products and the Internet, are triggering a reconsideration of methods, procedures and goals. We present a Multiagent System framework specialized in retail that addresses these changes with the use of rational agents and takes advantages of the new market opportunities. Like in an old bazaar, agents able to learn, cooperate, take advantage of gossip and distinguish between collaborators and competitors, have the ability to adapt, learn and react to a changing environment better than any other structure.

    Available-to-promise (ATP) systems: a classification and framework for analysis

    Get PDF
    Available-to-promise (ATP) systems deal with a number of managerial decisions related to order capture activities in a company, including order acceptance/rejection, due date setting, and resource scheduling. These different but interrelated decisions have often been studied in an isolated manner, and, to the best of our knowledge, no framework has been presented to integrate them into the broader perspective of order capture. This paper attempts to provide a general framework for ATP-related decisions. By doing so, we: (1) identify the different decision problems to be addressed; (2) present the different literature-based models supporting related decisions into a coherent framework; and (3) review the main contributions in the literature for each one of these. We first describe different approaches for order capture available in the literature, depending on two parameters related to the application context of ATP systems, namely the inclusion of explicit information about due dates in the decision model, and the level of integration among decisions. According to these parameters, up to six approaches for ATP-related decisions are identified. Secondly, we show the subsequent decision problems derived from the different approaches, and describe the main issues and key references involving each one of these decision problems. Finally, a number of conclusions and future research lines are discussed.Ministerio de Ciencia e Innovación DPI2007-6134

    Preliminary Draft Report: State-of-the-Art Review of Integrated Systems Control in the Steel Industry

    Get PDF
    This is a preliminary draft version of the report to be issued on the "State-of-the-Art of Integrated Systems Control in the Steel Industry". The draft is incomplete and not necessarily in final form. Its purpose is to provide background material for the IIASA Conference on "Integrated Systems Control in the Steel Industry" scheduled for 30 June to 2 July, 1975. A second purpose is to motivate feedbacks concerning omissions and additions generated by respondents and Conference participants which may be incorporated into the final 'report

    ERP system implementation in UK Joinery SMEs

    Get PDF
    The capabilities of an Enterprise Resource Planning (ERP) system to integrate all necessary business functions into a single system with a shared database efficiently and effectively has persuaded organisations to adopt them. Research shows that ERP implementation in both large and small to medium enterprises has been a difficult challenge for organisations throughout the years. Despite the many advantages of ERP systems, there isn t a clear and easy way of implementing them in Small to Medium Enterprises (SMEs). The motivation for the research is to investigate the barriers to ERP software system implementation in an SME using a case study approach, and to identify the steps to overcome these barriers and investigate the claim of ERP vendors that their ERP solutions improve the performance of their customers, the profitability and efficiency of work processes. This research identifies the barriers to ERP implementation in an SME, provides an overview of the traditional and current approaches of ERP implementation and discusses the effects of adopting an ERP system on the company s overall performance. The research uses a mix of methods including case study research and action research. Un-structured interviews and semi structured interviews approaches with negotiation and change management techniques were also used in order to generate knowledge concerning the problems at the case study. The case study has determined reasons for failed implementations, unlike previous research which suggests education level impact upon the implementation of the ERP system, the study demonstrates that an insufficient education level is not a necessary condition for resistance to change. It has also been shown in this research that high level management can have a direct influence on the ERP implementation in SMEs. This research suggests that SMEs need to standardize processes into business routines which will influence the introduction of a different knowledge store that helps the development of the new system; however employee s resistance to change, lack of trust of the new system and lack of knowledge has limited the implementation process by increasing mistakes and duplication of data. The ERP system has been evaluated by the end users at the case study organisation, and the results suggests that the implementation of an ERP system has improved the overall business and has increased the performance, the profitability and the efficiency of work processes. This research adds to the overall knowledge of ERP implementation in SMEs by deriving a better understanding of the problem in the body of knowledge and identifying the barriers to ERP implementation in SMEs. It provides recommendations that have been tested in the case study organisation for overcoming ERP implementation barriers in SMEs, and a financial model of the implementation costs and benefits. Finally, the recommendations presented in this thesis and suggested areas for further research set out the potential way forward to advance knowledge in this area

    Adult Supervision? Appellate Review, Mandamus, and the Federal Rules in Multidistrict Litigation

    Get PDF
    When a disaster of nationwide importance is dropped into the lap of a single federal judge as a multidistrict litigation (MDL), we expect a lot. The judge is supposed to efficiently manage the litigation as a massive aggregate, perhaps toward a workable resolution, while also still treating the cases transferred to the MDL as individual entities, respecting the rights and interests of the parties on both sides of the v. Doing so is a constant balancing act. Typically, and appropriately in our view, the MDL judge should be the one striking that balance day to day-with very limited interference. Indeed, that is how the MDL regime was designed. But increasingly it appears that defense-side interests would like more appellate review, largely in order to police supposedly lawless MDL judges. A prime example of this was the Sixth Circuit\u27s recent writ of mandamus against Judge Dan Polster in the gargantuan opioids MDL for, of all things, allowing plaintiffs to amend their complaint after a deadline in a case management order. In this Essay, we argue that this decision was wrong-both narrowly, as a matter of law, and broadly, as a matter of judicial policy. What\u27s worse, the Sixth Circuit\u27s opinion-and its implication that MDL judges ignore the Federal Rules of Civil Procedure-has gone viral, finding its way into briefs, opinions, and political materials intended to hamper judicial discretion in MDL. Here, we intend to counter this dangerous precedent-and narrative
