    On the Generality of the PERT Average Time Formula (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Decision sciences 20 (1989), S. 0 
    Details
    ISSN: 1540-5915
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Economics
    Notes: It is well known that the PERT average time formula approximation is related to the Beta distribution assumption. In this note, it is shown that if the formula is modified to use the median instead of the mode, then it becomes a good approximation regardless of distribution assumptions. Applications of the formula beyond project management are highlighted.

    Cost Efficiency Benchmarking for Operational Units with Multiple Cost Drivers (2000)
    Oxford, UK : Blackwell Publishing Ltd
    Decision sciences 31 (2000), S. 0 
    Details
    ISSN: 1540-5915
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Economics
    Notes: We consider the activity-based costing situation, in which for each of several comparable operational units, multiple cost drivers generate a single cost pool. Our study focuses on published data from a set of property tax collection offices, called rates departments, for the London metropolitan area. We define what may be called benchmark or most efficient costs per unit of driver. A principle of maximum performance efficiency is proposed, and an approach to estimating the benchmark unit costs is derived from this principle. A validation approach for this estimation method is developed in terms of what we call normal-like-or-better performance effectiveness. Application to longitudinal data on a single unit is briefly discussed. We also consider some implications for the more routine case when costs are disaggregated to subpools associated with individual cost drivers.

    Examining the relationship between business process improvement initiatives, information systems integration and customer focus: an empirical study (2005)
    Bradford : Emerald
    Business process management journal 11 (2005), S. 532-558 
    Details
    ISSN: 1355-2503
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: Purpose - The goal is to examine the relationship between business process improvement initiatives (BPII), information systems (ISs) integration, and customer focus. Design/methodology/approach - The data for the study were collected at the divisional levels from a list of "Fortune 500" firms. A total of 1,100 questionnaires were mailed to divisional managers and 115 responses were used for the data analysis. Findings - The results of this study support the hypotheses that BPII directly affects customer responsiveness and product/service innovation. In addition, data integration and communication networks flexibility are found to significantly affect customer responsiveness and product/service innovation. Communication networks connectivity did not have any significant effect on customer responsiveness and product/service innovation, respectively. Data integration, intrafirm networks connectivity and networks flexibility are found to significantly mediate the relationship between BPII and customer responsiveness and BPII and product/service development, respectively. Interfirm networks connectivity was not found to significantly mediate the relationship between BPII and customer responsiveness and BPII and product/service development, respectively. Research limitations/implications - The sample consists of divisions of Fortune 500 firms. Second, the study is cross-sectional; therefore, it lacks the predictive power to find the long-term effects of BPII and IS integration on customer focus. A longitudinal study can be a future research endeavor to validate the results of the study. Originality/value - To business managers, the study clarifies the role of IS integration in customer focus.

    Utilizing RISKOptimizer to manage quality performance (2001)
    Bradford : Emerald
    Logistics information management 14 (2001), S. 196-200 
    Details
    ISSN: 0957-6053
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: New software products are now available that offer solutions to operational problems that could not be handled by traditional linear programming. The problem of quality performance described could previously only have been handled by writing a special purpose simulation program. Now it can be solved in a spreadsheet environment using Evolver and RISKOptimizer software. Evolver can identify a global rather than a local optimal solution when non-linear relationships are present. RISKOptimizer takes the process one step further. It combines @RISK simulation capablity with Evolver's optimization algorithms to handle stochastic variables (uncertain demand and prices).

    Sudden Lost Meaning: A Catastrophe? (1994)

    Notes: Employees communicate more easily and are more committed to theorganization when beliefs and values are shared. Explores the phenomenonof sudden "lost meaning" - a situation in which individuals who stronglyshare the organization's culture appear suddenly to cease to identifywith the meanings and values to which they once strongly ascribed.Discovers two variables through examination of motivation theory.Proposes that these variables provide insight into sudden lost meaningand, consequently, suggest a framework for managerial behaviour.

    Optimal throughput for multistage input-output processes (2001)
    Bingley : Emerald
    International journal of operations & production management 21 (2001), S. 148-158 
    Details
    ISSN: 0144-3577
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: This paper considers productivity optimization for serial processes for which multiple outputs of one process become the inputs for the next process. Throughput planning amounts to deciding the relative proportions of outputs to target for production during a cycle. A linear programming model is proposed for optimal throughput planning. Illustrative data and computational results are shown.

    A review of naturalistic decision making research with some implications for knowledge management (2002)
    Bingley : Emerald
    Journal of knowledge management 6 (2002), S. 63-73 
    Details
    ISSN: 1367-3270
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Information Science and Librarianship
    Notes: In the last decade naturalistic decision making has been pursued by cognitive psychologists. The focus is on how human experts make decisions under conditions of time pressure and complexity; how they organize and use their knowledge is expected to provide principles for the emerging science of knowledge management. This paper surveys this research and discusses results, which indicate more attention needs to be given to: problem formulation; asking the right questions; use of teams; organization of knowledge; expanding scope of expert systems and case-based reasoning. Also the method, cognitive task analysis, which is generally used in naturalistic decision making is readily adaptable to business knowledge management.

    Deciding tuition structure with linear programming (1983)
    Springer
    Research in higher education 18 (1983), S. 359-371

    Notes: Abstract Revising tuition charges upward has become a regular annual exercise for many colleges and universities due to cost inflation. These occasions provide opportunities for modifying the structure of charges. One component of structure is the balance between per credit hour and per student types of charges. Another component is the differentiation of charges by program, or other student grouping. A linear programming approach is used here to suggest optimal increases under some broad policy constraints and certain necessary constraints dealing with consistency of the rates.

    Notes: Abstract By personal inventory decisions we mean the decisions on quantity purchased which are made daily in such activities as grocery shopping. This topic has previously been introduced only at the conceptual level. Hence our main purpose is to provide a quantitative discussion. Some specific models are pursued to solution. Surprisingly, a conjoint value function aggregator leads to indifference in replenishment quantity. Contrasts to the EOQ assumptions are highlighted.
