This paper examines the value of real-time traffic information to optimal vehicle routing in a nonstationary stochastic network. We present systematic approach aid implementation transportation systems integrated with technology. develop decision-making procedures for determining driver attendance time, departure times, and policies under time-varying flows based on Markov decision process formulation. With numerical study carried out an urban road network Southeast Michigan, we demonstrate...

Quality Function Deployment is a tool for bringing the voice of customer into product development process from conceptual design through to manufacturing. It begins with matrix that links desires engineering requirements, along competitive benchmarking information, and further matrices can be used ultimately link this manufacturing system. Unlike other methods originally developed in U.S. transferred Japan, QFD methodology was born out Total Control (TQC) activities Japan during 1960s has...

Several behaviourally relevant extensions of the standard decision analysis paradigm are generalized by model, and an inverse decision-aiding feature is included that permits use directly expressed preferences among alternatives. Parameter values (lowest-level-attribute utility scores trade-off weight) described set membership which can be used to describe many natural language expressions preference, interval descriptions value, ordinal cardinal rankings. Procedures presented for ranking...

In the product design and development process, quality function deployment (QFD) provides a comprehensive, systematic approach to ensure that new products meet or exceed customer expectations. This paper reports on results of survey more than 400 companies in United States Japan using QFD. The objective study was understand key factors result successful application research questions investigated this were developed both inductively from QFD case studies deductively literature. Regression...

We present new numerical algorithms and bounds for the infinite horizon, discrete stage, finite state action Markov decision process with imprecise transition probabilities. assume that probability mass vector each is described by a number of linear inequalities. This model imprecision appears to be well suited describing statistically determined confidence limits and/or natural language statements likelihood. The procedures calculating an optimal max-min strategy are based on successive...

The development of an interactive planning and decision support process for multiple-criteria alternative selection situations is discussed. Probabilities, utility scores the lowest level attributes, attribute tradeoff weights, i.e. parameters, can be imprecisely described by set inclusion. Within a specified structural model situation, allows decision-maker to iteratively select mix parameter value precision ranking specificity. By selecting this mix, able direct in iterative manner, using...

This paper studies the problem of optimally controlling a discrete-time production process with countable state space which is subject to one three control settings at each time interval: produce, inspect while producing, or repair (revise) process. The cost item produced and inspection costs are assumed dependent on It that inspector-decisionmaker receives imperfect on-line observations both times inspection. Bounds optimal obtained. For two-state case, several results associated...

Mobile communication technologies enable between dispatchers and drivers hence can fleet management based on real-time information. We assume that such capability exists for a single pickup delivery vehicle we know the likelihood, as function of time, each vehicle's potential customers will make request. then model analyze problem constructing minimum expected total cost route from an origin to destination anticipates responds service requests, if they occur, while is en route. this Markov...

Several important application areas that will dominate systems, man, and cybernetic (SMC) efforts for at least the next decade, together with methods require further research development in order to appropriately address these domains, are considered herein. More specifically, four broad pervasive system domains examined: service infrastructure transportation environmental energy defense space systems. Given nature of a number new systems [i.e., holistic-oriented, including system-of-systems...

Splitting loads such that the delivery of certain is completed in multiple trips rather than one trip results opportunities for a reduction cost and number vehicles used. Several studies have shown benefit split deliveries vehicle routing problem, which operating out depot makes series on each route. In this paper, we quantify using pickup problem. A heuristic to solve problem with developed applied set random large-scale instances, revealing potential loads. This reduced when real-world...

In this paper, we consider the problem of determining an optimal replacement strategy for a system subject to Markov deterioration, where decisions can only be made on basis noise-corrupted observations state. Three conditions are presented which guarantee that general case search limited control-limit strategies. Two these conditions, both straightforward generalizations assumptions due Derman, sufficient existence strategies completely observed (Derman's result) and unobserved (a new...

Last-mile logistics is an essential yet highly expensive component of city responsible for many nuisances in urban areas. Mobile access hubs are flexible consolidation and transshipment points aiming at creating more sustainable systems by dynamically using space as facilities. In this paper, we examine the potential mobile hub deployments parcel identifying impact design parameters on economic environmental performance. We propose a mathematical modeling framework integer program to assess...

A bimodal dial-a-ride problem (BDARP) considered in this paper is a that involves two transportation modes: paratransit vehicles and fixed route buses. Riders such system might be transferred between different modes during the service process. The motivation of research by efficiently coordinating with buses we can improve accessibility efficiency system. In paper, design decision support (DSS) which automatically constructs efficient vehicle routes schedules for BDARP. This DSS has been...
