Purpose To maintain road systems in the USA, state departments of transportation (DOTs) generally use in-house workers or private contractors. Limited studies have calculated the cost savings of hiring private contractors; however, most of them have not calculated cost savings based on life-cycle costs (LCCs). The purpose of this paper is to determine whether the LCC of chip seal and stripping maintenance activities performed by in-house workers are cheaper than those performed by private contractors. Design/methodology/approach The paper collected the hard cost data of chip seal and stripping maintenance activities performed by state DOT in-house workers, as well as private contractors, from 2003 to 2016 from the Nevada DOT Maintenance and Asset Management division. Statistical tests were conducted to test the research hypothesis that the LCC of chip seal and stripping activities performed by in-house workers are significantly less than those performed by private contractors. Findings The study results showed that the cost per unit and LCC of chip seal and striping work performed by in-house workers were significantly less than those performed by private contractors in Nevada. Research limitations/implications The study only collected data from Nevada DOT, so readers should use caution in generalizing the findings of this study. Additionally, factors affecting the cost of these maintenance activities for private contractors are significantly different compared to in-house contractors. Therefore, these differences may be some of the potential reasons for cost difference between these two methods. Practical implications The practical implications of this study are that state DOT engineers need to plan for outsourcing chip seal and stripping maintenance activities only to private contractors that are cost effective, based on life-cycle cost. Originality/value The LCC analysis framework developed in this study will help state DOT engineers to determine cost savings by using in-house workers for road maintenance works.

Беспилотные воздушные суда и беспилотные авиационные системы становятся частью повседневной жизни, в том числе в деятельности органов и учреждений уголовно-исполнительной системы. В статье исследован исторический аспект появления беспилотных воздушных судов в России и зарубежных странах, необходимость, типовые задачи и особенности правового регулирования использования беспилотных воздушных судов в уголовно-исполнительной системе. Однако ряд вопросов до настоящего времени является предметом дискуссии и требуют правового регулирования. Современные технологии позволяют оснастить беспилотные воздушные суда различными приборами, придающими им дополнительные функциональные характеристики: приборами видео- и фотофиксации, тепловизором, громкоговорителем, оружием. В зарубежных странах сложилась разная практика регулирования: от разрешения использования беспилотных воздушных судов с оружием в правоохранительной деятельности и уголовно-исполнительной системе (США, Великобритания и др.) до протестов гражданского общества и требований законодательного запрещения использования беспилотных воздушных судов, способных причинить вред человеку. Не решены вопросы в части регулирования порядка сбора, обработки, передачи и хранения (в том числе длительности хранения) информации, полученной в ходе видео- и фотофиксации, включая передачу информации, содержащей персональные данные гражданина, в частности, его изображение. Обсуждается вопрос о соблюдении прав человека и гражданина, в том числе осужденного, при получении и использовании информации, полученной при помощи беспилотных воздушных судов в деятельности органов и учреждений уголовно-исполнительной системы. Требуется внесение изменений в процессуальное законодательство в части регулирования использования данных, полученных при помощи беспилотных воздушных судов, как доказательств, а также в целом их юридическое значение в административном, уголовном, гражданском (арбитражном) процессе. Необходимо урегулирование вопросов ответственности сотрудников уголовно-исполнительной системы, которые могут превысить полномочия с помощью использования беспилотных воздушных судов. В рамках Национальной технологической инициативы происходит активное развитие рынка АэроНет, поэтому беспилотные воздушные суда в деятельности уголовно-исполнительной системы могут стать частью этого рынка. Unmanned aerial vehicles and unmanned aircraft systems are becoming part of everyday life, including in the activities of bodies and institutions of the penal system. The article examines the historical aspect of the appearance of unmanned aerial vehicles in Russia and foreign countries, the need, typical tasks and features of the legal regulation of the use of unmanned aerial vehicles in the penal system. However, a number of issues are still the subject of discussion and require legal regulation. Modern technologies make it possible to equip unmanned aerial vehicles with various functional characteristics, ranging from video and photo capture, the availability of a thermal imager, a loudspeaker, to weapons. In different countries, different regulatory practices have developed: from allowing unmanned aerial vehicles with weapons in law enforcement and the penal system (USA, UK, etc.) to civil society protests and the requirements of the legislative prohibition on the use of unmanned aircraft that can cause harm to humans. Unresolved issues regarding the regulation of the procedure for collecting, processing, transferring and storing (including the duration of storage) of information obtained during video and photo recording, including the transmission of information containing personal data of a citizen, including its image. The issue of observing the human rights of a citizen, including a convict, is discussed when receiving and using information received by unmanned aerial vehicles in the activities of bodies and institutions of the penal system. Amendments to the procedural legislation are required in terms of regulating the use of data obtained by unmanned aerial vehicles as evidence, as well as in general their legal significance in the administrative, criminal, civil (arbitration) process. It is necessary to resolve the issues of responsibility of employees of the penitentiary system, which may exceed their authority through the use of unmanned aerial vehicles. As part of the National Technological Initiative, the AeroNet market is actively developing, therefore unmanned aerial vehicles in the activities of the penitentiary system can become part of this market.

The 2030 climate and energy framework includes EU-wide targets and policy objectives for the period 2021–2030 of (1) at least 55% cuts in greenhouse gas emissions (from 1990 levels); (2) at least 32% share for renewable energy; and (3) at least 32.5% improvement in energy efficiency. In this context, the methodology of the cost-optimal level from the life-cycle cost approach has been applied to calculate the cost of renovating the existing building stock in Europe. The aim of this research is to analyze a pilot building using the cost-optimal methodology to determine the renovation measures that lead to the lowest life-cycle cost during the estimated economic life of the building. The case under study is an apartment building located in a mild Mediterranean climate (Castellon, SP). A package of 12 optimal solutions has been obtained to show the importance of the choice of the elements and systems for renovating building envelopes and how energy and economic aspects influence this choice. Simulations have shown that these packages of optimal solutions (different configurations for the building envelope, thermal bridges, airtightness and ventilation, and domestic hot water production systems) can provide savings in the primary energy consumption of up to 60%.

Abstract This study develops a method to capture the broadest customer preference in a product line while minimizing the life-cycle cost of providing variety. The paper begins with an overview of product variety and its importance in overhead costs: supply chain, equipment and tooling, service, and recycling. After defining the product structure graph as a representation of variety, the paper introduces an approximate measure for the customer importance and life-cycle cost of product variety The cost measure utilizes the concept of late point identification which urges standardization early in the manufacturing process and differentiation at the end of the process. The variety importance-cost map allows engineers to identify cost drivers in the design of the product or the manufacturing system and seek improvements. The refrigerator door example illustrates the concept. On-going work seeks to validate and enhance the method with several companies from different industries.

This paper presents a review of research in the area of life cycle costing and offers a critique of current commercial cost estimation systems. The focus of the review is on relevant academic research on life cycle cost from 2000 onwards. In addition to this a comparison of the current cost estimation systems is presented. Using the review findings and industrial investigations as a base, a set of mathematical representations for design and manufacturing costs and the introduction of the critical factors is proposed. These are considered in terms of the operational, maintenance and disposal costs to create a method for ascertaining the life cycle cost estimate for complex products. This is presented using as an exemplar, research currently being undertaken in the area of low volume and long life electronic products in the UK defence sector. The benefit of the method proposed is that it aims to avoid the inflexibility of traditional approaches which usually require historical and legacy data to support the cost estimation processes.

In order to make the best use of the defense spending budget, it is critical that the Department of Defense (DoD) accurately predict the Research, Development, Test and Evaluation (RDT&E), Procurement, and Operation and Support (O&S) costs down to the third level of the Work Breakdown Structure for Major Defense Acquisition Project (MDAP) wheeled or tracked vehicles. This research utilizes historical data, extracted from government databases, to develop cost estimating relationships (CERs) that predict the life cycle cost of wheeled and tracked vehicles based on attributes. This research can also be leveraged for defense acquisition programs across the DoD portfolio. The model will be integrated into a tradespace analysis tool, ERS & CREATE-GV, which was developed by ERDC to predict the cost of each alternative created in the tradespace.

This chapter examines the role of unmanned aerial vehicles (UAVs) in the delivery of medical and emergency supplies to remote areas. It outlines a number of potential considerations for operators wishing to use UAVs to deliver medical and emergency supplies to remote areas. These considerations address a number of practicalities in terms of the organisation that is wishing to conduct such operations, the operations themselves, and the technology that is used for such operations. These considerations primarily stem from the nature of the international regulatory framework for unmanned aircraft operations and the peculiarities of using a UAV to deliver medical and emergency supplies. The chapter will outline some of the practicalities that have been worked through or are being worked through during a project to deliver medical and emergency supplies in Northland, New Zealand. This will provide readers with examples of some of the real-world considerations that operators face as well as outline the positive community impact that such operations can provide.

Currently, repair and maintenance cycles that follow the completion of construction facilities lead to the necessitation of subsequent data on the analysis of study and plan for maintenance. As such, an index of evaluation was drafted and a plan of maintenance cycle was computed using the investigation data derived from surveying target housing units in permanent rental environmental conditions, with a minimum age of 20 years, and their maintenance history. Optimal maintenance and replacement methods were proposed based on this data. Economic analysis was conducted through the Risk-Weighted Life Cycle Cost (RWLCC) method in order to determine the cost analysis of maintenance life cycle methods used for repair. Current maintenance cycle methods that have been used for 20 years were also compared with alternative maintenance cycles.
