In this paper, a method is presented to combine financial data and financial statements for economic analysis, which consequently introduces a software application for determining the economic structure of a cement factory. This software converts nearly 300 items of raw data of a cement factory to almost 4 times more economic-analytic information. The software analyzes the quantity and quality of production activities in addition to the cost structure of the concerned cement factory. It provides more than 80 descriptive figures, which have been defined previously and are applied to illustrate the economic structure of the cement factory. The calculated tables and figures are able to guide decision makers of the cement factory with regard to inefficiencies, obstacles, and various problems in the factory. In the end, a set of policies for increasing production efficiency and reducing costs are expressed briefly, which can be considered as the primary plans to operationalize the analytical information of the software. It is worth to mention that the presented structure of the software has been designed for Abyek Cement Factory. However, it can be employed as a guiding project for other cement factories as well. In other words, the software can be rebuilt with consideration of their specific information by revising and adjusting the software structure to cover their specific features.

Production of high precision circular scales is a complicated process requiring expensive equipment and complex processes to achieve. Precision angle measurement equipment tends to be very expensive and therefore not accessible to all in need. Simplification of production of such devices can lead to reducing costs of angle measurement systems ensuring easier accessibility. A new method of producing precision circular scales using low cost mass production can reduce the costs of these devices drastically. Therefore, utilising a common CD technology as the basis for such scales is analysed. This paper deals with the analysis of the newest laser cutting method for plastic circular scales. Preliminary results of manufacturing such scales are presented in the paper as well as measurements of the grating of the scale were performed. The quality of different scales manufactured using different laser types is analysed in the study. The cost – effective alternative of manufacturing circular scales is discussed in the paper.

The Impact

Purpose – Non-technical dimensions such as spatial quality are just as relevant for energy efficiency as technical and economic dimensions in the renovation of dwellings. However, the significance of non-technical dimensions is often neglected in the energy renovation of dwellings. The purpose of this paper is to demonstrate how the renovation of dwellings for energy efficiency influences spatial quality in the MS-1 building in the neighbourhood of Arlequin, Grenoble, France. The Arlequin case study is part of the ZenN project, nearly zero energy neighbourhoods, funded by the European 7th Framework Programme (Grant Agreement No. 314363). Design/methodology/approach – The impact of the renovation on spatial quality is analysed by crossing technical measures, applied in the energy renovation of dwellings with the definition of spatial quality proposed by Acre and Wyckmans (2014). The spatial quality definition results from a literature review on quality of design and urban life, wherein works of Weber (1995) and Gehl (2010, 2011) are related to the residential use in the scales of the building and block. The impact of renovation on spatial quality is further evaluated by using the spatial quality assessment developed by Acre and Wyckmans (2015). The impact on spatial quality is observed by considering all the renovation measures, instead of only considering the measures primarily related to energy performance. This emphasises the need for a cross-disciplinary approach between technical and non-technical dimensions in the energy renovation of dwellings. Findings – The results display both negative and positive impacts of the energy renovation on spatial quality in the dwellings and emphasise the potential of non-technical dimensions in promoting renovation. The impact on spatial quality is primarily negative when only measures adopted in order to improve energy efficiency are considered in the evaluation. Originality/value – This paper consists of a novel crossing of technical and non-technical dimensions in energy renovation of dwellings. The work aligns with the current European trend of nurturing energy-deep renovation to reach Europe’s 2050 energy-efficiency targets (Buildings Performance Institute Europe (BPIE) 2011).

Clear Statement

In project management, the project scope is the base of significant project planning processes such as estimating the cost, schedule and building work breakdown structure. Poor project scope definition directly affects project cost and schedule. Accordingly, dealing with unrealistic scope definition of cost and schedule may lead to failing a project. Besides, changes in project scope have a negative and positive impact on project success. This paper aims to predefine the potential scope changes to keep the project scope on track and identify any weakness in scope definition at the early stages of a project. Enhancing project scope quality has a massive impact on the success of a project and it adds more control over project scope. A method is proposed to improve the quality of project scope and increase the efficiency of controlling scope changes. The proposed method will help to avoid scope creeping by defining a clear statement of work, increase the learning opportunities of the development team to optimize its processes, reducing the communication gap between the clients and development team and screen adjustments of new tasks. The proposed method is validated using a survey and the results are found encouraging.

Technical Readiness

Technical operation of lifting and transport equipment is one of the key problems of ports and terminals. The functions of technical operation include maintenance and repair of lifting and transport equipment. The imperfection of the maintenance and repair system leads to downtime of lifting and transport equipment, which affects the cost of loading and unloading operations. The main requirements for technical operation are to ensure the quality and speed of loading and unloading operations with minimal operating costs. One of the indicators for assessing the quality of technical operation is the coefficient of technical readiness, which shows that the probability that the lifting and transport equipment will be in a working state at any time, except for periods in which operation is not provided. These periods include the time when the lifting and transport equipment is being maintained and repaired. Technical operation strategy is selected based on the technical readiness coefficient.
