A Multivariate Intervention Model for the Dutch Mint Circulation: Estimation and Monte Carlo Simulation

For each of the five Dutch coinage denominations, a transfer-function model is estimated. The output variables are monthly observations of coins in circulation. Two input variables represent transaction flows; all other inputs are step functions, representing the occurrence of interventions. Using the method of cross-correlating the residuals of the individual equations, a multivariate transfer-function model is constructed and estimated. Next Monte Carlo simulation is applied to derive expectations and variances of the yearly addition to the stock of coins until 1996. Our results enlighten on some aspects of a problem situation faced by the Dutch State Mint.     

Aligning supply chain collaboration using Analytic Hierarchy Process

The significance of collaboration among supply chain members has been sufficiently stressed in the recent literature as a powerful tool for increasing accuracy of demand forecasts and for consequent cost reductions. Since it has been recognized that naïve forecasting is no longer cost efficient, Supply Chain (SC) members have found it very important to exchange relevant information that will help improve accuracy of demand forecasting. This information differs widely in terms of their characteristics. For example, some information (e.g. historic sales data) that is cheap to exchange may not contribute to a great increase in forecast accuracy. Similarly, some information may not be very reliable (e.g. demand forecast by individual SC members). In general, there is a trade-off in the kind of information required and the kind of information exchanged. This study analyses these trade-offs using an Analytic Hierarchy Process (AHP) model. The model is then implemented based on case studies conducted in two manufacturing firms. The AHP model ranks available information in terms of their contributions to improve forecast accuracy, and can provide vital clues to SC partners for preparing exchangeable data. From the case studies using AHP model, it was proved that using the preferred SC data, the firms could enhance forecasts accuracy. This in turn can help the firms to make decisions on SC collaborative arrangements for information exchange.     

企业社会责任构建的原则和对策——以海西企业为例

政府和社会各界对企业推进社会责任建设日益关注。当前,企业社会责任建设在取得一些成绩的同时,还存在诸多不足之处。企业社会责任的构建应坚持社会各界积极参与原则、循序渐进原则、依据企业情况区别对待原则、以人为本原则、大力弘扬历史文化原则。要强化企业社会责任,须将软环境建设作为突破口,构建与企业类型、层次相适应的社会责任模式,并着力强化企业工会的职能作用。     

A step-by-step guide to the identification of an appropriate computer-aided production management system

The increasing dissatisfaction of users with their Computer-aided production management (CAPM) systems has been widely reported. This dissatisfaction led the UK's Science and Engineering Research Council to initiate a major study to improve CAPM systems use. The research results presented here form part of the overall initiative and focus on the development of a set of guiding principles for companies seeking to implement appropriate CAPM systems. The research team have identified three key elements that must be considered when implementing a CAPM system. First, that CAPM implementation can be eased if the overall manufacturing-system is first simplified. Second, we recognize that even then most companies will still require a computerized solution thus any methodology must include a software specification. Third, the overall performance of the system may be enhanced by changes to the infrastructure that supports the software. In attempting to meet these requirements the research team developed a four-stage methodology. The first two stages of the methodology deal primarily with the strategic context for CAPM, i.e. the simplification. The last two stages develop a software specification and present guidelines for the development of appropriate infrastructure configurations.     

New Indices of Money Supply and the Flexible Laurent Demand System

The article begins by surveying the existing results on the new Divisia monetary aggregates. Charts display the differences in behavior between the Divisia aggregates and the Federal Reserve's official simple-sum monetary aggregates. The article then compares system-wide fit for the simple-sum and Divisia monetary aggregates when used as data in the joint estimation of a system of demand equations. The demand system is derived from a new Laurent expansion approximation to the reciprocal indirect utility function. The Laurent expansion provides a better-behaved remainder term than that of the more commonly used Taylor series. The results favor the Divisia aggregates.     

Information sharing in a supply chain with a make-to-stock manufacturer

We study ex ante information sharing in a supply chain consisting of a downstream retailer and a make-to-stock upstream manufacturer. The retailer has imperfect demand information and may choose to share it with the manufacturer. Based on the information sharing arrangement, the manufacturer makes the wholesale price and the stocking level decisions. Then the retailer decides the order quantity and the manufacturer fulfills the order up to the available stock level. We find that the retailer has an incentive to voluntarily share the information with the make-to-stock manufacturer if the magnitude of demand uncertainty is intermediate. This stands in sharp contrast with the existing studies which show that the retailer never shares information when the manufacturer is make-to-order. Our results highlight the interdependence between the retailer׳s incentive to share information and the manufacturer׳s operational and marketing decisions.

Fusion Product Planning: A Market Offering Perspective*

Devices that integrate multiple functions together are popular in consumer electronic markets. We describe these multifunction devices as fusion products as they fuse together products that traditionally stand alone in the marketplace. In this article, we investigate the manufacturer's fusion product planning decision, adopting a market offering perspective that allows us to address the design and product portfolio decisions simultaneously. The general approach adopted is to develop and analyze a profit‐maximizing model for a single firm that integrates product substitution effects in identifying an optimal market offering. In the general model, we demonstrate that the product design and portfolio decisions are analytically difficult to characterize because the number of possible portfolios can be extremely large. The managerial insight from a stylized all‐in‐one model and numerical analysis is that the manufacturer should, in most cases, select only a subset of fusion and single‐function products to satisfy the market's multidimension needs. This may explain why the function compositions available in certain product markets are limited. In particular, one of the key factors driving the product portfolio decision is the margin associated with the fusion products. If a single all‐in‐one fusion product has relatively high margins, then this product likely dominates the product portfolio. Also, the congruency of the constituent single‐function products is an important factor. When substitution effects are relatively high (i.e., the product set is more congruent), a portfolio containing a smaller number of products is more likely to be optimal.
