In a multi-product production system, the cycle time is described as the time that the slowest workstation takes to process the mix of products (Martinich, 1997). Johri (1987) presented a linear programming model to estimate the capacity of a production line manufacturing a variety of products without accidental stoppages of the workstation. The multi-product system is able to follow a predeter...

Although the simple assembly line balancing problem (SALBP) is the topic of many studies, typically they either consider minimizing the number of stations for a given cycle time (called type one), or minimizing the cycle time for a given number of stations (called type two). Rarely, type E of the problem has been considered. In the type E, cycle time and number of stations are both decision var...

Two approaches to defining almost-invariant surfaces for magnetic-fields with imperfect magnetic surfaces are compared. Both methods are based on treating magnetic field-line flow as a 1 :-dimensional Hamiltonian (or Lagrangian) dynamical system. In the quadratic-flux minimizing surface approach. the integral of the square of the action gradient over the toroidal and poloidal angles is minimize...

this paper presents a new mathematical model for the problem of scheduling part families and jobs within each part family in a flow line manufacturing cell where the setup times for each family are sequence dependent and it is desired to minimize the maximum completion time of the last job on the last machine (makespan) while processing parts (jobs) in each family together. gaining an optimal s...

This paper investigates the interaction between the economics of production and imperfections in the production process. SpeciÞcally, this paper is the Þrst to devise a model in an attempt to provide managers with guidelines to choose the appropriate production run times to buffer against both the production of defective items and stoppages occurring due to machine breakdowns. In addition to pr...

Professional sports franchises have used the lure of economic riches as an incentive for cities to construct new stadiums and arenas at considerable public expense. An analysis of taxable sales in Florida cities demonstrates that none of the 6 new franchises or 8 new stadiums and arenas in the state since 1980 have resulted in a statistically significant increase in taxable sales in the host me...

Abstract American states differ in their protection of workers, acceptance organized labor, dominant industrial cultures, and regarding labor unions’ capacity political power. In this article, I examine declining union membership the analyze various laws that limit power unions assess consequences these developments. also document explain a recent resurgence organizing, resistance, work stoppag...

This paper presents a fuzzy extension of the simple assembly line balancing problem of type 2 (SALBP-2) with fuzzy job processing times since uncertainty, variability, and imprecision are often occurred in real-world production systems. The jobs processing times are formulated by triangular fuzzy membership functions. The total fuzzy cost function is formulated as the weighted-sum of two bi-cri...
