Abstract

Purpose

Measurement uncertainty is present in all measurement processes in the field of production engineering. However, this uncertainty should be minimized to avoid erroneous decisions. Present methods to determine the measurement uncertainty are either only applicable to certain processes and do not lead to valid results in general or require a high effort in their application. To optimize the costs and benefits of the measurement uncertainty determination, a method has to be developed which is valid in general and easy to apply. The paper aims to discuss these issues.

Design/methodology/approach

This paper presents a new technique for determining the measurement uncertainty of complex measurement processes. The approximation capability of artificial neural networks with one hidden layer is proven for continuous functions and represents the basis for a method for determining a measurement model for continuous measurement values.

Findings

As this method does not require any previous knowledge or expertise, it is easy to apply to any measurement process with a continuous output. Using the model equation for the measurement values obtained by the neural network, the measurement uncertainty can be derived using common methods, like the Guide to the expression of uncertainty in measurement. Moreover, a method for evaluating the model performance is presented. By comparing measured values with the output of the neural network, a range in which the model is valid can be established. Combining the evaluation process with the modelling itself, the model can be improved with no further effort.

Originality/value

The developed method simplifies the design of neural networks in general and the modelling for the determination of measurement uncertainty in particular.

Abstract

The City of Bradford Metropolitan Council is one of the new Councils to appear as a result of the 1974 Local Government organisation. It has wide ranging responsibilities, including the provision of Education, collecting of refuse, repair of highways, housing etc. It employs just under 24,000 employees, and has a manpower budget of well over £100 millions.

Abstract

The role of uncertainty in manpower planning is discussed and illustrated by reference to manpower planning in the Civil Service. The nature of the planning process is described, and an account given of the principal statistical methods employed. Uncertainty is classified in terms of random error, specification error, estimation error and data error. Strategies for containing error are discussed, and examples used to illustrate the relative importance of each type. Parameter specification error is usually dominant, and experience suggests that sensitivity analysis is the most practical way of dealing with it. The mutually‐dependent roles of statistician and manager in the process of working towards effective decisions, and the importance of a flexible and continuous planning process which can adapt to the unexpected, are both stressed.

Abstract

FOLLOWING the initial development of Convair's delta‐winged aircraft, a new concept of fuel tank design became imperative because it is necessary to use every available cubic inch of space for fuel storage in relatively thin wings.

Abstract

Efficient manpower planning has been recognized as a critical aspect for the development of an economy. In 2001, the Works Bureau of the Hong Kong SAR Government (predecessor of Environment, Transport and Works Bureau) commissioned an HKPolyU consultancy team to develop a computer‐based model to estimate the demand for different categories of construction personnel. This article presents the concept and features of the manpower demand‐forecasting model developed for the construction industry of Hong Kong. The forecasting model is formulated on the basis of the labour multiplier approach by deriving the relationship between the number of workers required and the project expenditure in the given project duration. Multipliers for 61 project types were derived for 38 labour trades using completed project data. The labour demand by occupation for each project can then be estimated by multiplying the corresponding multipliers and the estimated project expenditure. Several unique features of the model have been developed, including “normalization” and “contract cost adjustment factor”. Normalizing the labour multipliers can facilitate the prediction of occupational labour requirements at different stages of a construction project. The adjustment factor is introduced to eliminate the discrepancy between the original estimates and final contract values so as to enhance the estimation accuracy. The model can also be used to predict the number of jobs created for a given level of investment. The government can apply this model to check and compare which project types will generate most jobs before committing public money. This model could be easily adopted and adapted by foreign construction authorities while planning manpower.

Abstract

THE structural design of the VC10 has been based on well‐established principles and the philosophy of low stress levels in the skins and secondary load paths to meet ‘fail‐safe’ conditions. In general a multiple load path type of structure has been employed. In any one of these load paths a crack may be allowed to develop without fear of catastrophic failure. The operator will, however, be required to maintain a high standard of inspection of the structure in order to prevent cracks developing concurrently in these multiple load paths. The operating economy will be greatly enhanced since major components will not require to be changed until the whole of their useful life has been utilized. This was not the case in structures of the ‘safe‐life’ type owing to the large factors which had to be imposed on life.

Abstract

Manpower planning is a key aspect of the human resource management function in organizations. Specifically, manpower planning examines the gap between staff availabilities (internal and external to the organization) and staffing requirements (to perform tasks in the organization) over time, and prescribes courses of action to narrow such a gap. Different perspectives in manpower planning have each been studied widely in the past. However, few insights are available on the interactions among these perspectives and the impact of these interactions on the resultant manpower plans. Describes these interactions in the form of decision and feedback loops. From this description, derives an integrated decision support system (DSS) framework for manpower planning. Also presents a methodology for analysis of the manpower planning business process and feasibility assessment of DSS deployment. The system framework and analysis methodology constitute a basis for applications deployment and consultancy undertaken by the author’s institute.

Abstract

INTRODUCTION It has become almost mandatory to start a text on manpower planning with a debate on the definition of the subject. (For a good example see Thakur[8].) There is a wide range of opinion and confusion on the topic of what manpower planning is. In this review I will concentrate on describing, collating and appraising the recent work which has been called Manpower Planning and the definition of the subject will therefore be the net coverage of the work reviewed. As an aid to the reader unfamiliar with the subject, the following preliminary definition is offered as a starting point: “Manpower planning is a strategy for matching future manpower numbers and skills with organisational activities”.

Abstract

FOR a number of years, a considerable amount of research and experimental effort has been expended on the problem of approach and landing of aircraft in operational circumstances where the visual references and the atmospheric conditions are below the levels considered safe for the pilot, assisted only by conventional instrumentation.
