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     

Lebensstile und Wohnstandortwahl

Life style research and various disciplines dealing with regional studies argue that life styles are explanatory relevant for decisions in different behavioral areas, in particular for residential choices. However, the results of previous research are rather mixed. To specify the conditions for the explanatory relevance of life style based preferences for locational choices, this article ties in with a parsimonious decision theoretic model, which has been applied both in the sociology of the city and in life style research. Based on this theoretical framework an empirical study is presented, which tests the explanatory relevance of life styles for residential choices. The study is based on neighborhood survey data from Leipzig, representing a context, in which a strong impact of life styles may be expected. However, even in this context the empirical study shows rather limited explanatory power of life style based preferences for residential choices, whereas household arrangements and economic resource endowments of persons show much more explanatory power.     

Changing informal institutions via mimesis: Gender equality in marriage proposals

Marriage equality has exposed how the institution of marriage is changing, but less attention has been given to how informal institutions around heterosexual marriage rituals are affected by a growing demand for gender equality. By applying institutional theory and feminist institutionalism to the context of women proposing to their male partners, this paper observes how shifts in gender norms change heteronormative institutions. Drawing from interviews with women who proposed to men and a virtual ethnography, we describe how reverse proposals can set precedence for emulation of practices or mimetic isomorphism. We therewith contribute to institutional theory in threefold ways. First, we describe how mimetic isomorphism introduces new standards and norms into a highly traditional institution. Second, we show how this integration of new standards and norms serves this patriarchal institution to remain relevant and appear progressive. Finally, we contend that this tension of joining a patriarchal institution but doing so in a subversive manner represents a double bind for women who are encouraged by society to formalize their heteronormative relationships through marriage and yet chastised for initiating this themselves.     

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.
