Institutionalization of a management science innovation in police departments

Article Abstract:

A survey was undertaken of 17 police departments, five years after they implemented a patrol car allocation model (PCAM). Extent of use and organizational adaptation were examined. There were few signs overall that PCAM had a major effect on police patrol allocation management. PCAM was found to be working in six of the 17 departments, and fully institutionalized in two of them. Recommendations for enhancing the long-term effect of future modeling projects are offered, based on use and non-use patterns. It is suggested that user needs should be surveyed; that users have a larger role in model development; that models be designed for an expanded range of tasks operable on microcomputers; and that performance evaluation and feedback be included in all model-constructing projects.

Sequencing to minimize work overload in assembly lines with product options

Article Abstract:

A sequencing method for minimizing overload in paced assembly lines characterized by customer-specified options is presented. The existence of product options, which is common in the automobile industry, can greatly increase the number of products that customers can order. The objective is to develop a sequencing system to maximize the entire amount of work completed or minimize the overload. An optimal procedure for the case in which one station is affected by an option is presented, along with a heuristic procedure for multiple stations.

Approximation of the overflow process from a G-M-N-K queueing system

Article Abstract:

A two parameter method is employed for asymptotic approximation of the overflow process from a G-M-N-K queueing system that has a stationary counting arrival process, Markovian service times, K waiting spaces, and N parallel homogeneous servers. Numerical results are offered and comparison is made between approximation outcomes and those obtained from a simulation study.
