A generalized congestion function for highway travel

Urban planners designing the optimal scale and pricing of highway services must pay close attention to the choice of the functional form used to describe the relationship between highway speed and the volume of roadway traffic. This congestion relationship is a crucial empirical fact for planning. While past work have posited a variety of speed-volume models, no successful efforts have been made to statistically compare the different specifications. This paper presents a generalized congestion function (GCF) which allows us to select the preferred (by a maximum likelihood criterion) speed-volume specification. The most prominent previous speed-volume models are all shown to be special cases of GCF. Failure to use the GCF approach may be very costly. For example, in the design of highway tolls the switch from the optimal GCF specification to a statistically “second-best” model may lead to a consumer surplus loss of $1 million annually for a typical urban area.     

The (Re)Making of Polycentricity in China's Planning Discourse: The Case of Tianjin

Polycentricity is promoted as an ideal urban form to achieve sustainable and balanced development, and it has been widely adopted by planners in China, especially in large cities. However, the rhetoric about polycentricity has rarely been interrogated in planning research in terms of scales, contextuality, power and rationality. To fill this gap, we carried out a Foucauldian discourse analysis in our research to interpret the nature of polycentric practice in City Master Plans, using Tianjin as a case study. Through an analysis of how the discourse of polycentricity is being deployed in planning documents, we develop two principal arguments in this article. First, the conceptual substance of polycentricity evolved alongside the urban transition process in China, and its discursive practice involved multiple scales and spatial elements. Secondly, rather than being mere technocratic practice, the production and legitimation of distinct discourses of polycentricity is an articulation of multi-scalar power involving various stakeholders, which is disguised and justified by the planning profession.     

Capacity planning techniques for manufacturing control systems: Information requirements and operational features

Substantial interest has been focused on techniques that determine the amount and timing of work center capacity to satisfy the master production schedule. Although several techniques have been developed for preparing work center capacity plans, very little analysis of the operational features and the application of these techniques has been reported. Four techniques, capacity planning using overall factors (CPOF), capacity bills, resource profiles, and capacity requirements planning (CRP), vary substantially in their complexity and the level of detail required to plan work center capacities. All four procedures require the use of the master production schedule to develop a capacity plan, but some have much more demanding data requirements. Important differences are the means by which capacity requirements are estimated by the techniques and the manner in which the bill of material, manufacturing lead time and inventory status information are incorporated into the capacity plan. The purpose of this paper is to describe the operational features of the four capacity planning techniques, the underlying data base requirements, and some key managerial issues in choosing among these techniques.     

Planning rapid transit networks

Rapid transit construction projects are major endeavours that require long-term planning by several players, including politicians, urban planners, engineers, management consultants, and citizen groups. Traditionally, operations research methods have not played a major role at the planning level but several tools developed in recent years can assist the decision process and help produce tentative network designs that can be submitted to the planners for further evaluation. This article reviews some indices for the quality of a rapid transit network, as well as mathematical models and heuristics that can be used to design networks.

A strategy,structure, human resource database: OASIS

Traditionally, strategic planners and human resource professionals have taken separate approaches in their attempts to improve organization functioning. As a result, strategic planners lack important information that affects the implementation of their plans and human resource managers have little impact on the strategic direction of their orgnizations. The University of Michigan, Hay Associates, and The Strategic Planning Institute have come together in a new venture to build a multicompany database that links organization characteristics and human resource and strategic planning practices with data on company financial performance. The database will be used to make intercompany comparisons on significant organization variables and to identify those practices that lead to improved financial performance.

The “systems view” and planning theory

This paper evaluates the British “systems view” of planning in terms of its success in providing a basis for planning theory. It is argued that it falls short of fulfilling all the criteria of a satisfactory base for planning theory, i.e. it does not provide a rationale for physical planning. Instead of making full use of the potential for criticising their practise inherent to its concept, the systems view merely rationalises what physical planners do anyway. In an attempt to investigate what the rationale of physical planning might be, the author then suggests one should conceive physical development plans as resource budgets which act mainly as constraints on, rather than as guides for, action.     

Recessionary actions and absence: A workplace-level study

Actions such as work restructuring and wage and employment freezes taken by organizations in response to recessions are widely assumed to decrease employees' job security and detrimentally affect perceptions of management's trustworthiness. We assess whether these effects occur and if, in turn, they affect workplace absenteeism. Using data from Britain's Workplace Employee Relations Survey 2011, we show that the effects on stress-based absence are limited and not as predicted, but the effects on withdrawal-based absence are strong and as predicted. Reductions in well-being or job security's effect on well-being did not affect absence, and while the reduction of trust perceptions' effect was to increase anxiety, anxiety did not increase but reduced absenteeism. The effects on withdrawal absence differ: those of recessionary action through job security reduce absenteeism, while those through trust perceptions increase it, both as predicted. The two effects involving trust perceptions are less pronounced when recessionary actions are accompanied by voluntary layoffs, but not by compulsory layoffs. The implications for management are that they should be more conscious of the effects on absence when planning recessionary actions, and more generally their effects on presenteeism.     

Too much of a good thing: The impact of product variety on operations and sales performance

We examine the impact of product variety decisions on an operational measure – unit fill rate – and on sales performance. Results are estimated using weekly data over three years from 108 distribution centers of a major soft drink bottler. Our results show that fill rates are negatively associated with product variety at a diminishing rate. In addition, we examine the total effect of product variety on sales including both the direct effect and the indirect effect through operations performance. The total impact of product variety on sales initially is positive, although at a diminishing rate. However, beyond a certain level, increased product variety actually results in lower sales; that is, “too much of a good thing”. Thus, the findings provide a comprehensive understanding of the impact of product variety on operations and sales performance.     

Business process monitoring via decentralized complex event processing

ABSTRACT

Complex event processing (CEP) techniques have been used for business process (BP) monitoring of large organizations with high number of complex BPs and high rates of BP instance generations resulting in high number of monitoring rules and high rates of events. To circumvent the scale limitation of centralized CEP techniques, we present a decentralized CEP mechanism called dBPM that uses both task parallelism by decomposition and distribution of monitoring rules, and data parallelism by partitioning and dispatching of events. We show that dBPM is more scalable than a general distributed CEP mechanism, called VISIRI, by dynamically adapting to workload changes.     

Long-term forecasting of fuel demand at theater entry points

Managing the distribution of fuel in theater requires Army fuel planners to forecast demand at the strategic level to ensure that fuel will be in the right place, at the right time, and in the amounts needed. This work presents a simulation approach to forecasting that accounts for the structure of the supply chain network when aggregating the demand of war fighters across the theater over the forecasting horizon. The resulting empirical distribution of demand at the theater entry point enables planners to identify forecast characteristics that impact their planning process, including the amplitudes and temporal positions of peaks in demand, and the estimated lead time to the point of use. Experimentation indicates that the forecasts are sensitive to the pattern of war fighter demand, the precise structure of the in-theater supply chain network, and the constraints and uncertainty present in the network, all of which are critical planning considerations.     

Analysing Place and Place‐making: Urbanization in Suburban Oslo

Despite developments within planning theory challenging the ideal of the rational master plan it may be argued that there is still use for the production of knowledge through analysis in planning. However, the cultural complexity of today's planning contexts, and a move towards governance and entrepreneurial policies, makes it difficult to make places, to achieve social welfare and sustainability. Traditionally, the analysis of places has been done by architects and planners focusing on physical form, having an essentialist perspective of place resembling the theory of genius loci. In Norway, the planning authorities refined this methodology in the 1990s. This approach is, however, not in tune with a progressive view of places as multiple and dynamic social constructions, and may be accused of ‘symbolic violence’. If one is to take this view seriously and still be able to make plans, planning must also be based on other types of knowledge. In this article I argue for a socio‐cultural approach to reveal social representations and practices that make a place. I use the case of place‐making in Sandvika, a suburban ‘minicity’ outside Oslo, as an example of how a constructivist understanding differs from and may supplement an essentialist approach.     

Planning in the smaller city: Major problems and a possible solution

The study is based on interviews with 29 mayors, 26 planning commission chairmen and 23 professional planners in an Eastern state. It presents the four major problems confronting planning in these communities: (1) a lack of official commitment to planning, (2) the “gap” between professional planners and municipal officials, (3) an underdeveloped advocacy for planning and (4) several indigenous community hindrances. Each problem is examined in detail and a framework for dealing with resistance to planning is proposed.

Capacity utilization and the shift coefficient in Soviet planning

Conclusion In the eighties greater emphasis has been placed on intensification of growth in the Soviet Union. Soviet planners are now confronted with the task of improving their knowledge of existing capacity and their means of control over both capacity utilization and expansion. Imperfect knowledge has become a major hindrance to a better allocation of resources. Information is limited and biased. The ministries tend to overestimate capacity utilization by excluding from the estimates of their equipment machines in storage or recently installed. The CSA's statistics are biased by inadequate statistical methods and by the reliance on physical indicators. They tend to overestimate actual capacity and consequently to underestimate capacity utilization.Amongst the available indicators on capacity utilization, planners focus more on the shift coefficient. All industry is presently under pressure to increase this coefficient. However in most engineering branches the equipment shift coefficient is estimated on the basis of enterprises' data on workers' attendances, which—however stable the capital labour ratio may be—cannot give evidence of idle equipment due to technical, organizational and other factors, which could be conventionally defined planning failures and that official censuses on capacity utilization show to be increasingly important. Thus the confidenence on information obtained through the estimated shift coefficient may lead to misplacing the emphasis on a human factor, e.g. on voluntarism. Labour shortages may not be a crucial factor for incomplete capacity utilization as long as most industry works on a two shift regime. But a higher shift regime, particularly in branches with prevalent female labour, may provoke increasing turnover and need for auxiliary repair and servicing personnel, which may jeopardize the policy of intensification. Coeteris paribus the utilization of the workers shift coefficient as a proxy for the equipment shift coefficient may have been justified as long as the capital labour elasticity of substitution was almost nil. However, increasing automation and computerization may aggravate the problem of obtaining correct information on shift and intra-shift capacity utilization. Intrashift capacity utilization may even decrease when the shift regime increases. If decisions on writing off capacity were taken on the basis of a falling workers' shift coefficient, enterprises could be induced to renounce advance technology, in favour of traditional equipment. This, in turn, could aggravate the problem of labour shortage.In default of a proper system of information, planners need to focus on the functioning and achievements of leading industry, which is more closely monitored. One may assume that this section of industry works with automated technology and is at the forefront of the process of adapting the industrial apparatus to present day technological requirements.University of Verona, Verona, Italy.

Planning in Turbulent Times: Exploring Planners' Agency in Jerusalem

This article explores the role of planning in the deeply divided and politically polarized context of Jerusalem. The overall argument developed throughout the article is that the relation between planning and politics is a non‐hierarchical set of interactions, negotiated within specific historical, geographical, legal and cultural contexts—in other words, orders don't come down from the politicians to be slavishly followed by planners. In this respect our findings, based on in‐depth interviews with Israeli planners, suggest that the case of Jerusalem represents a particularly dramatic illustration of the fact that the function of planning expertise can only be understood in relation to the surrounding socio‐political environment. Furthermore, contrary to conventional wisdom, planners in Jerusalem are not destined to either complicity or irrelevance in the face of political imperatives; planners' agency, however, does not simply reflect their mastery of specific professional knowledge and tools, but also their ability to act strategically in relation to the context in which they operate.
