摘要：To date, it is unclear as to how Environmental Management Systems (EMS) are implemented and what effects these systems have on other environmental and operational practices. This study reports empirical insights to EMS practices based on the largest EMS survey of manufacturing firms in the United States. The objective of the study is to test for a relationship between environmental management systems and perceived operations performance while considering direct and indirect effects of various ...

摘要：We study the deterministic time-varying demand lot-sizing problem in which learning and forgetting in setups and production are considered simultaneously. It is an extension of Chiu's work. We propose a near-optimal forward dynamic programming algorithm and suggest the use of a good heuristic method in a situation in which the computational effort is extremely intolerable. Several important observations obtained from a two-phase experiment verify the goodness of the proposed algorithm and the ...

摘要：Only a small set of employee scheduling articles have considered an objective of profit or contribution maximization, as opposed to the traditional objective of cost (including opportunity costs) minimization. In this article, we present one such formulation that is a market utility-based model for planning and scheduling in mass services (MUMS). MUMS is a holistic approach to market-based service capacity scheduling. The MUMS framework provides the structure for modeling the consequences of a...

摘要：ISO 14001 constitutes a major dilemma for many American firms. This new standard holds the promise of waste reduction and better process management, but the benefits and costs are very difficult to predict. This study attempts to identify and explain antecedents impacting the decision to pursue certification for some of the first plants certified in the United States. Using data from a large survey of U.S. managers and a Logit analysis, we find the factors influencing management decisions to a...

摘要：An important issue being discussed for Chilean pine plantation policies is the application of environmental protection measures when managing its timber areas. Typical measures, already in place in more developed countries, include imposing riparian strips and protecting fragile soils from the use of heavy machinery. While environmental protection measures have been considered vital for decades, so far there has been almost no attempt to quantify both the benefits and costs of these measures. ...

摘要：In this paper we review the literature on appointment policies, specifically in terms of the objective function commonly used and the assumptions made about the behavior of demand. First, we provide an economic framework to analyze the problem. Based on this framework we make a critical analysis of the objective functions used in the literature. We also question the validity of the assumption made throughout the literature that demand is exogenous and independent of customers' waiting times. W...

摘要：A critical component of service strategy in high-contact environments is service encounter management. Effective service encounters are a result of the quality of employee development, including systems for work and job design, training and development, and attention to employee well being. Results of empirical analysis indicate that service strategies reflecting the dimensions of employee development drive employee outcomes such as productivity and satisfaction. Employee outcomes are signific...

摘要：Manufacturing organizations can potentially improve environmental management both by increasing the level of investment in environmental technologies and by shifting that investment away from pollution control and toward pollution prevention. However, managers must not only consider their own manufacturing operations in isolation, but also those of others along the supply chain. This paper explores two dimensions of supply chain activities-collaboration and evaluation-that might be leveraged b...

摘要：The disposal of hazardous wastes creates major economic and environmental problems. One productive use of hazardous wastes is to blend them into fuel, which mitigates damage to the environment by recycling waste into fuel and reducing fossil-fuel consumption. Operations personnel face a daunting task of efficiently blending hazardous waste into fuel, while simultaneously maintaining environmental regulatory requirements. This research develops a goal-programming approach to the waste-fuel-blen...
