TL;DR: In this paper, the authors examined the significance of social cost benefit analysis in justifying alternative levels of output to be achieved by the London Transport Executive (TRRL) in order to select and examine certain policy changes.
Abstract: This study selects and examines certain policy changes in order to provide insights into the significance of social cost benefit analysis in justifying alternative levels of output to be achieved by the London Transport Executive. The results are presented of four types of case study: 1, A global evaluation of fare and service changes in buses and underground, viewing these activities as a whole; 2, Separate closure of three underground stations; 3, Change of service levels in two underground lines (Jubilee and Victoria); and 4, Substantial change in service provided by certain bus routes, selected for their variability in results.

TL;DR: In this paper, the authors reviewed measures of inventory service levels both for single and multiple items, and compared single item measures during lead times to their overall counterparts, and showed that overall measures are not only more relevant to customers but also require lower safety stock from the provider of the goods.
Abstract: Inventory service levels are a concern of every inventory system. Poor service levels may result in loss of customers and sales, whereas excessive service levels result in loss of money due to large inventories. Although inventory service levels have been discussed widely in the professional literature, the emphasis has been on service levels during replenishment lead times. Overall service levels, which are much more relevant to customers, have received little attention, and the results presented are often mistaken. This article reviews measures of inventory service levels both for single and multiple items, relates single item measures during lead times to their overall counterparts, and shows that overall measures are not only more relevant to customers, but also require lower safety stock from the provider of the goods.

TL;DR: In this paper, the effects of three workforce strategies on a multistage, multiproduct manufacturing system under various operating conditions were analyzed. And the results showed that none of the strategies had significantly different workforce sizes and that the level-flexible strategy was most insulated from the seasonality, inventory restrictions and service level.

TL;DR: Measurement techniques that were developed to track these important service level attributes in the IBM Information Network (IBM/IN) and apply to most complex SNA networks are described.
Abstract: A key requirement in the network service business is that specified service levels be managed to the end user's satisfaction. The capability to measure and report end user response time and availability is essential. This paper will describe measurement techniques that were developed to track these important service level attributes in the IBM Information Network (IBM/IN). These techniques apply to most complex SNA networks.

TL;DR: In this paper, the authors propose a cost-effective service contracting strategy for public transportation. But, the authors do not consider the impact of the cost on ridership and the quality of service.
Abstract: The continuing increase in public transit costs must be checked in order for transit to control deficits and thereby maintain affordable fares, usable service levels and ridership. There is no surplus of public funding for transit; urban areas are, on the contrary, characterized by great mobility needs. Deficit control is the most critical issue facing public transportation today. Gaining control of deficits requires substantial changes. Public transit must become more open to innovative and cost effective service alternatives, and less committed to the product forms and delivery mechanisms of the present, or its decline will continue. Private transportation operators are characterized by low costs, and are being effectively used in public transportation service in many localities. The savings achieved through contracting are substantial. Through contracting, public transit agencies can reduce deficits, while continuing to provide service to the community. The public, which pays the cost in fares, taxes and service reductions, is entitled to obtain full value for that cost. It is entitled to an unencumbered consideration of cost effective transit alternatives, including service contracting.
