Real-time software methodologies: Are they suitable for developing Manufacturing control software?

Computer-Integrated Manufacturing (CIM) systems may be classified as real-time systems. Hence, the applicability of methodologies that are developed for specifying, designing, implementing, testing, and evolving real-time software is investigated in this article.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45553/1/10696_2005_Article_BF01358949.pd

Developing manufacturing control software: A survey and critique

The complexity and diversity of manufacturing software and the need to adapt this software to the frequent changes in the production requirements necessitate the use of a systematic approach to developing this software. The software life-cycle model (Royce, 1970) that consists of specifying the requirements of a software system, designing, implementing, testing, and evolving this software can be followed when developing large portions of manufacturing software. However, the presence of hardware devices in these systems and the high costs of acquiring and operating hardware devices further complicate the manufacturing software development process and require that the functionality of this software be extended to incorporate simulation and prototyping.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45542/1/10696_2005_Article_BF01328739.pd

Pragmatic issues in conversions of database applications

The need to convert database applications from one DBMS to another arises frequently. This paper presents a cost/benefit evaluation model for the database conversion problem, applies this model to several situations involving convertion of large database applications and proposes a decision support system for database conversion decisions. It also points out that although most of the literature focuses on database models and structures, in practice organizational and human considerations play a key role in the conversion of database applications and may become a limit to the growth of new database applications.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28364/1/0000129.pd

An Investment Decision in a Life Insurance Company

The paper shows the development of the after-tax earnings from interest as a function of the proportion of money invested in each type of security and certain other parameters such as the interest yields and the tax rate. This function is then differentiated and the optimum point determined. A procedure is provided for computing the optimum proportion. "Management Technology", ISSN 0542-4917, was published as a separate journal from 1960 to 1964. In 1965 it was merged into Management Science.

An Analysis of Criteria for Investment and Financing Decisions Under Certainty

The objective of this paper is to investigate the decision-making procedure for accepting or rejecting investment or financing alternatives available to the firm. The properties of the decision rules based on discounted present value and internal rate of return are studied for the class of projects described by a finite sequence of cash flows. The necessary and sufficient conditions under which the decision rules lead to unique solutions are derived. Where the decision rule does not provide a unique solution, it is necessary to define two rates: the project investment rate and the project financing rate. The extension of the project analysis in terms of the two rates permits the derivation of unambiguous decision rules for all projects. The relevance of the results is discussed in the summary.

Mathematical Analysis of Rates of Return Under Certainty

The purpose of this paper is to prove certain properties of the present and future values of a sequence of cash flows which have applications in the theory of capital budgeting. This is done in Theorems III, IV and V. As an introduction, certain previously available results about the present value function are stated and proved as Theorems I and II. A summary of the relevance of these results in capital budgeting is given in the Summary.
