A closed loop automatic scheduling system (CLASS)

Abstract

CLASS is a production scheduling system, that is designed to function in either a stand-alone manner, or in conjunction with an MRP system. MRP systems innately do not have 'closed loop’ capability in the sense of being able to produce master schedules and order releases that are consistent and that respect capacity constraints. True closed loop performance requires detailed scheduling. In addition to interfacing with MRP systems, CLASS is designed to produce schedules that can be used in conventional shops or can be downloaded to automated facilities. The design goals for the system, its internal architecture, and its role in manufacturing control systems are described. The modelling and decision capabilities     

We Are the Corporation: Dispersive CSR

We contend that the current trend of emphasis on corporate social responsibility (CSR) serves to divert the public's attention from the real ethical issues facing business and society. We extend the scope of social responsibility beyond business corporations to include a range of institutions. We also propose that CSRs be reconceptualized in terms of the ways that managers enable stakeholders to hold themselves and each other responsible for the ways their actions affect each other as they conduct business through the firm. In this article, we propose a new view of corporations and responsibility that reconstrues behavior currently referred to as CSR. Starting with an overview of theories of the firm, we show that the way in which a firm is conceived yields different views on CSR. A shortcoming of the theory of the firm approach to CSR is that it leads us to focus excessively on business corporations at the expense of a broader analysis of other institutional players. These theories also tend to emphasize the obligations of corporations to people rather than of people to each other. We propose that social responsibility be viewed through a systems theory paradigm instead. We then argue that corporations should be construed in terms of the people who impact them. We advance a different conception of business responsibility that is more comprehensive, inclusive, and systemic.     

MONEY DEMAND AND QUANTITY CONSTRAINTS: EVIDENCE FROM THE SOVIET INTERVIEW PROJECT

This paper examines the effects of shortages on the demand for money of Soviet citizens. It is the first to examine the demand for money in a centrally planned economy using cross-section data in which alternatives to income and interest rates are used to explain money demand. We find demand for broad money and liquid assets depends on income, illiquid wealth, participation in the underground economy, and the severity of quantity constraints as well as demographic factors. Our findings show that quantity constraints decrease demand for the national currency and increase demand for convertible currencies and barter transactions.     

1979–1982: RULES OR DISCRETION IN MONETARY POLICY?

What determined MI growth from November 1979 through October 1982? A reaction function is developed and tested which ascribes the level of M1 to two Fed motives. One is the Fed's desire to hit its money growth targets, the other is to carry out a counter-cyclical short-run monetary policy. Both motives are found to be significant during the period. This evidence is consistent with the contention of some economists that the period was not a valid test of monetarist policy rules.     

The individual economic well-being of Native American men and women during the 1980s: A decade of moving backwards

The study examines whether the income opportunities of Native Americans over the 1980s improved in response to stronger aggregate job growth or deteriorated in response to declining wage and employment opportunities, particularly for the less-skilled. Using data from the 1980 and 1990 US Census on individuals aged 16–64, a methodology is presented to analyze the effect of changes in the income distributions of Native Americans and whites on the average Native American-white income ratio. Oaxaca-type decompositions are also used to yield insights into the role of economy-wide as opposed to Native American-specific effects on changes in income, hourly earnings and annual hours employed over the period. The study concludes that the economic circumstances of Native American men and women further deteriorated relative to whites over the decade, chiefly due to the declining valuation given to Native American human capital, particularly for men. An important finding of the study is the role of economy-wide vis-à-vis native-specific effects: almost all of the adverse movements in average hourly earnings against Native Americans can be attributed to changes in economy-wide hourly earnings structures (with the least-skilled being paid less), whereas the large fall in relative annual hours is due to changes specific to Native Americans.     

ALL-TERRAIN VEHICLES: MARKET REACTION TO RISK INFORMATION

This article examines the market response to new risk information implicit in a recent regulatory stop-sale of new three-wheeled all-terrain vehicles. A hedonic price analysis is used to quantify the stop-sale's impact in the secondhand market, a market segment not directly affected by the stop-sale. The analysis shows a substantial reduction in the price of three-wheeled all-terrain vehicles relative to the price of less risky models. This result is consistent with rational economic behavior and suggests that providing new risk information can improve market effciency.
