The Cost

A methodological approach to forecasting the cost costs at the main stages of the life cycle of a sample of weapons and military equipment, as one of the most important carriers of the capabilities of military organizational-staff formations, is proposed, which is carried out when substantiating measures for developing the capabilities of troops in the course of long-term and medium-term defense planning. The methodological approach is based on the use of the concept of a typical distribution of the cost of the life cycle of a sample by stages and stages, which allows in a formalized form to link costs at each stage of the purchase price of a serial product of a sample of weapons and military equipment of a specific type and type, taking into account the choice of a specific way of obtaining weapons and military equipment. It is proposed to forecast the volume of necessary costs at the stage of operation and support, taking into account the uneven distribution of these costs during this stage of the life cycle of a separate product. For this, it is proposed to divide the entire period of the duration of the operation stage into two main parts. The first part corresponds to the operating conditions of the product with a constant failure rate of the equipment after the completion of a short running-in process, and the operating costs per unit of time on it are considered the same throughout its duration. A formalized expression is proposed for obtaining the predicted value of these costs depending on the purchase price of the product. In the second part of the period of operation and support of a product of weapons and military equipment, operating costs per unit of time change over time according to an exponential law, reflecting the fact that operating costs increase with an increase in the failure rate as it approaches the assigned service life, which corresponds to the laws, known from the general theory of reliability of technology. The specifics of forecasting the costs of operation and support of a product obtained by import and which has already been in operation and has a residual service life have been determined.

The current problem of ensuring energy saving and improving the energy efficiency of buildings and structures for agricultural purposes is identified. The geopolitical situation, import substitution programs and agricultural development programs set the task of developing domestic vegetable production, which in its turn requires the construction of new vegetable store buildings, as in most regions of Russia the harvest is collected once a year. In this regard, the current task is to ensure the energy conservation and achieve high energy efficiency of the vegetable store buildings. Energy saving is the basic technology for creating effective agriculture. The purpose of the study is to analyse the requirements for insulation materials for buildings and vegetable store facilities, taking into account energy efficiency and life cycle cost. The authors analysed the criteria for choosing a heater for the vegetable stores: low coefficient of thermal conductivity, water absorption, sorption humidity, frost resistance, biostability, lack of cold bridges, long service life. It is proposed to supplement the criteria for choosing a building insulation with the characteristics of the life cycle cost and the service life. Design and construction of agricultural buildings is proposed to be implemented using the concepts of BLC and BIM, the use of which gives an opportunity to design buildings with optimal energy efficiency parameters and take into account the cost of the life cycle. The cost of the buildings life cycle is the main of all the performance indicators when comparing alternative design options that differ by the application of advanced technologies and material resources and the contractors' offers when concluding contracts not only for purchase, but for servicing the subject of trades during its service life. The conclusions are made about the advantages of using foamed polyethylene foam for warming vegetable store buildings, as well as the conclusion about the expediency of adding criteria determining the sustainable development of the human environment, namely life cycle cost, service life, recycling ability. The formula for calculating the cost of the buildings life cycle, adapted to the specificity of buildings for agricultural purposes, is given.

One of the major operational costs of phosphorus recovery as struvite is the cost of caustic chemical that is added to maintain a desired level of operative pH. A study was conducted at the Lulu Island Wastewater Treatment Plant (LIWWTP), Richmond, BC, using a struvite crystallizer and a cascade stripper designed at the University of British Columbia (UBC). The stripper was tested under different operating conditions to determine the effectiveness of CO2 stripping in increasing the pH of the water matrix and thereby reducing caustic chemical use. This reduction is expected to reduce the operational costs of struvite production. Throughout the project, a high percentage (90%) of phosphorus removal was achieved under each condition. The cascade stripper was very effective in saving caustic usage, ranging from 35% to 86%, depending on the operating conditions. However, the stripper showed relatively poor performance regarding ammonia stripping.

Service Life Cycle

This chapter presents a first attempt to realize a methodological framework supporting the most relevant phases of the design of a value-added service. A value-added service is defined as a functionality of an adaptive and multichannel information system obtained by composing services offered by different providers. The framework has been developed as part of the multichannel adaptive information systems (MAIS) project. The MAIS framework focuses on the following phases of service life cycle: requirements analysis, design, deployment, and run-time use and negotiation. In the first phase, the designer elicits, validates, and negotiates service requirements according to social and business goals. The design phase is in charge of modeling services with an enhanced version of UML, augmented with new features developed within the MAIS project. The deployment phase considers the network infrastructure and, in particular, provides an approach to implement and coordinate the execution of services from different providers. In the run-time use and negotiation phase, the MAIS methodology provides support to the optimal selection and quality renegotiation of services and to the dynamic evaluation of management costs. The chapter describes the MAIS methodological tools available for different phases of service life cycle and discusses the main guidelines driving the implementation of a service management architecture called reflective architecture that complies with the MAIS methodological approach.

The costs borne by road infrastructure authorities for managing and maintaining road devices such as safety barriers may be very high. This has prompted the need for identifying and analysing in detail all factors that influence the costs of safety barriers throughout their service life. To meet that need, the authors used international experience and field data collected under the LifeRoSE project to define the cost structure and, as a next step, to analyse factors that are relevant to the costs actually incurred.

The Cost

Constructions for water withdrawal are the constitutive building industry component. The cost of these constructions is rather high. That is why while designing it is necessary to choose optimal design model and operating conditions during design life. Operation experience showed that the wells are desirably placed along one line to provide the most optimal conditions for water withdrawal. While designing the wells interaction is considered as a group operation if the distance between them is less than two radiuses of influence. Such wells disposition allows reducing the area and cutting down the investments for water withdrawal construction and also creating the better conditions for equipment and mains operation. Design of interacting wells consists of finding the tube well number, the distance between them, the discharge and levels (static and dynamic). At operating condition determination, it is necessary to consider the combined action of pure water reservoirs and tube well.

Objective: To determine the optimal elevation of the outer rail in a curved track section based on technical and economic criteria, calculating the life cycle cost using the methods of life cycle re-source management, risks, and reliability analysis (URRAN methodology). Methods: The authors used multivariate analysis, point estimation, the probability theory and mathematical statistics, the theory of reliability of technical systems, the URRAN methodology, field observations of the condi-tion of the curved track sections and the scope of work during their maintenance. Results: A model of the overhaul cycle of a curved track section has been developed. The dependences of the change in the intensity of the accumulation of faults and the cost of track maintenance during the overhaul cycle on the average values of undamped train accelerations when moving along the sur-veyed sections are presented. The optimal values of undamped acceleration are determined for various operating conditions of railway curves, which provide the minimum track maintenance costs. The authors have found that the minimum cost of the overhaul cycle is the factor for choos-ing the optimal undamped acceleration during the overhaul cycle. The optimal elevation of the out-er rail has been calculated and the actual values in the investigated sections have been analyzed. The method’s economic efficiency is calculated in the form of the ratio of the difference between the costs of the overhaul cycle for the actual and optimal elevations of the outer rail. Practical im-portance: Optimization of the elevation of the outer rail will enable minimizing the intensity of the accumulation of faults and, therefore, reduce the cost of maintenance on the track. The total cost of routine track maintenance will be reduced by 5–10 %.

A model of the optimal maintenance period for repairable product after warranty expiration under renewing warranty is proposed. In the process to fulfilling warranty, the failures of product within warranty period happen randomly, the replacements of products successively failed with warranty period form a renewing process. Given failure rate of product, the period of fulfilling warranty is function of warranty period. User purchasing a product is considered an investment; the period of fulfilling warranty and the maintenance period after warranty make up the life cycle of product investment. Taking various cost factors into account, making model of the cost rate in life cycle of product investment under renewing warranty, the cost rate is function of maintenance period. Give the failure rate of product is an increasing function, it is derived that there is unique optimal maintenance period minimizing the cost rate. Finally, numerical example is given for illustration.
