코로나-19로 인한 스포츠지도자들의 경제적 어려움과 안전망 확보를 위한 과제

The purpose of this study is to reveal in detail the loss of work opportunities and economic damage experienced by sports coaches during the COVID-19. And based on the results, it was intended to present a task for building social safety net for sports coaches. For this study, 9 incumbent sports coaches who 3 or more years of teaching experience were chosen as research participants, and the study was conducted through the case study method. In-depth interviews and literature studies were used to collect research data. The results of this study are as follows. First, sports coaches suffered serious economic damage due to COVID-19. Many sports coaches did not work for at least six months a year, resulting in economic damage of more than tens of thousands of won. Second, as non-working periods are prolonged due to COVID-19, sports coaches have had to find other means of livelihood. They made up for their losses through part-time jobs at logistics center of online retail companies and delivery agencies, and bank loans, and earned income by renting private facilities for lessons. Third, disaster subsidies, freelance subsidies, subsidies by local governments, disaster subsidies for small business owners, and loans for small business owners were provided as government subsidies. However, the government subsidy did not help much because the damage was large while facilities closed over a year. Fourth, the weak social employment safety net of the sports coach job was revealed during the COVID-19 outbreak. Institutional action is needed to enable sports coaches to participate in employment insurance program. Fifth, during the COVID-19, sports coaches and workers in the sports industry suffered great damage, but did not receive much support from the government. One of the reasons is the lack of an agenda leader representing the damage and difficult realities of the sports industry. This study has significances in that it recorded vivid cases of sports coaches who suffered difficulties due to COVID-19 through field research.

Strategic Planning for Green Logistics Implementation in Potato Agro-Industry

Indonesia is the largest potato producer in Southeast Asia. Annual production averaged 1.09 million tons. However, productivity is still low, ranging from 16.4 - 18.22 tons/ha. The objective of this study was to propose a strategic planning of the Green Logistic Distribution Center (GLDC) in the potato agro-industry using Interpretative Structure Modeling (ISM). A contribution of this research was that we used ISM to analyze the sustainability policy of the green logistics program which includes social, economic, and environmental issues. The result showed that the objectives such as availability of raw materials (1), supplier of potato (3), market place (5), traffic transportation (7), economic factor (8), and environmental issue (9) include variable linkages from the system. Every action on these objectives will result in a successful GLDC program, while the lack of attention to these objectives will lead to program failure. In this case, the driver power is large but has little dependence on the program. While the other sub-elements of purpose are categorized as dependent, this is interpreted more as a result of other objective actions. With two forms of information, ISM and DP-D matrix diagrams, the deepening of the GLDC program is made possible to support strategic planning.

Regional logistics centre: Application to Eastern Canada

The recent difficulties of the wood industry in Canada (decline of the pulp and paper sector, decline in available fiber volume, 2008–2009 housing crisis, etc.) and mounting pressures for a more efficient use of natural resources make it all the more relevant to examine how to make better use of the forest resource. In this regard, the creation of sorting and consolidation yards, distinct from forest sites and mills, offers multiple opportunities for value maximization and cost minimization. This article aims to better understand the interaction between a forest logistics center and a complex forest network while exploring several geo-economic factors favoring the use of such a structure. A profit maximization model is proposed and applied for a case study in the Mauricie region of Quebec, Canada. The results showed that a logistics center would increase the profit by $0.90 (Canadian dollars) for each cubic meter of wood available for harvesting, notably through an increase in the volume of wood processed into finished products of up to 83,000 m3 annually (or 4.6%). A dynamic effect of up to 17% was also observed between the operation of a processing yard and the use of load returns.

Prerequisites For The Establishment Of Transport And Logistics Centres On The Basis Of Railway Stations

Kazakh and foreign economists note that the decline in industrial and agricultural production, stagflation of the economy of the Republic of Kazakhstan in the post-crisis period require a deep analysis of the current situation and careful development of appropriate economic and managerial decisions. In these circumstances, it is necessary to find the most effective ways out of the crisis.It is obvious that it makes no sense for the Republic of Kazakhstan to fully follow the centuries-old path of becoming an industrially developed country. Without a doubt, the modern market economic system should serve as a reference point, which, in addition to free competition, also has numerous internal and external levers of management and regulation, including state ones, which in their essence suppress bursts of fluctuations in the market element and allow using all the advantages and advantages of market relations.One of these ways in the market economy, according to many experts, with whom it is difficult to disagree, is the design of logistics models, the formation, implementation and organization of the rational functioning of logistics services, structures, management systems at the on-farm, industrial (micro logistics) and macroeconomic, international, national, regional (macro logistics) levels, the widespread development and application of logistics methodology, technologies and tools, creation of logistics management systems that differ in their functional purpose and organizational and economic level.When integrating the economy of the Republic of Kazakhstan into the world economic community, there is an increasing need to create reliable, dynamic and efficient domestic logistics management systems that could optimally interact with the national logistics systems of foreign countries in international economic and logistics processes at the macro - and micro logistic levels.These logistics systems are designed to facilitate the rational movement of any flows of information, goods, capital and people both within the country and across the borders of States, taking into account the national peculiarities of customs clearance and support.

Locating abrupt disaster emergency logistics centres using improved artificial bee colony (IABC) algorithm.

Emergency management is conceptualized as a complex, multi-objective optimization problem related to facility location. However, little research has been performed on the horizontal transportation of emergency logistics centres. This study makes contributions to the multi-objective locating abrupt disaster emergency logistics centres model with the smallest total cost and the largest customer satisfaction. The IABC algorithm is proposed in this paper to solve the multi-objective emergency logistics centres locating problem. IABC algorithm can effectively calculate the optimal location of abrupt disaster emergency logistics centres and the demand for relief materials, and it can solve the rescue time satisfaction for different rescue sites. (1) IABC has better global search capabilities to avoid premature convergence and provide a faster convergence speed, and it has optimal solution accuracy, solution diversity and robustness. (2) From the three optimal objective function values obtained, the optimal objective function values obtained by IABC algorithm are obviously better than ABC and GABC algorithms. (3) From the convergence curves of three objective functions the global search ability and the stability of IABC algorithm are better than those of ABC and GABC algorithm. The improved ABC algorithm has proven to be effective and feasible. However, emergency relief logistics systems are very complex and involve many factors, the proposed model needs to be refined further in the future.

Determining the subgrade reaction modulus. Mathematical approach on case study

Subgrade reaction modulus (k) is the reaction pressure sustained by the soil sample under a rigid plate of standard diameter per unit settlement measured at a specified pressure or settlement. For the design of industrial slabs, the geotechnical engineer should provide two values for the subgrade modulus: the first value will be used for short-term loadings such as lift-truck wheel loads, and the second value will be used for long-term loadings such as uniform storage loads or wide area rack. Unfortunately, there are no direct laboratory procedure in order to determine the value of the subgrade reaction modulus, the only way to determine the value is by field tests or by correlation with other tests. The most common used field test is the plate bearing test. The paper is based on a case study, conducted on a site located in Romania, Maramures county. In order to verify the slab base and to determine the value of k, plate tests according to German norm DIN 18134 were performed on the site of a large logistics center in Baia Mare. Two methods were used for the interpretation of the data from the tests performed on the site. The first method is based on a program designed in Excel, and the second method is based on a program written in Qt Creator, using C++ programming language. At the end a comparison was made between the results obtained with the two use methods. The interpretation procedure presents a series of difficulties based on the form of the resulting function. These issues were addressed in the present study.

운영자원 규모 및 고객서비스 수준을 동시 고려한 운송 라우트 설계

Purpose Among the costs incurred by operating a logistics center, shipping costs vary depending on changes in international oil prices, development of vehicle technology, and optimization of delivery routes. As a result, they suggest ways to reduce shipping costs. Methods In this work, we propose a study that provides a delivery network design that can be considered in the design of a real delivery network by deriving an optimal solution that satisfies the objective function through genetic algorithms. Results The experimental results showed that the increase in operating resource t is highly correlated with operating cost and CSL. As the increase in operating resource t decreases the trend of CSL growth, the establishment of operating resource to maintain CSL 100% is very inefficient. Conclusion For companies considering changes in logistics network design and operation resources, it was important to establish mid-term or long-term business plan targets for companies and to find and make decisions where logistics operating costs and CSLs conflict to an appropriate level.

A variable-scale dynamic clustering method

With the high intensity and density of aerospace launch in China, aerospace project materials management faces various challenges, such as multiple aerospace projects concurrent, high supply timeliness and high quality level. Although several enterprises have successfully explored a versatile material management regulation for multiple aerospace projects, the low inventory turnover problem still exist due to the difficulty in versatile material recognition and inventory distribution. This paper studies the dynamic inventory management problem of aerospace project materials. Firstly, a numerical concept space model is established to describe the data characteristics of aerospace project materials. Then, we propose the variable-scale clustering algorithm based on the numerical concept space, which is utilized to automatically recognize versatile materials. Also, the obtained satisfy scale feature supports managers making inventory-related decision. Finally, a dynamic adjustment algorithm of inventory classification based on the variable-scale clustering is proposed, in order to dynamically maintain the inventory management plan of aerospace project materials. Experiments select the inventory data of aerospace project metal materials during Jan 1, 2015 to Mar 31, 2018 from the logistics center in China Academy of Launch Vehicle Technology. And experiment results illustrate that our proposed variable-scale clustering algorithm has high efficiency and practical application value in solving dynamic inventory management problem of aerospace project materials.

OPTIMIZATION OF FREIGHT FORWARDING SUPPORT FOR INTERNATIONAL TRANSPORT CORRIDORS

With the modern development of the economy and foreign economic relations, a new approach to cargo flows, their distribution and, directly, to the development of transport is required. At the current stage of foreign trade growth, the classic approach of the logistics system in the medium and long term requires a deep and qualitative revision, this is necessary for long-term development, although this approach will still work for the current period and in the near future. Of course, we need to use new technologies to reach goals of optimization all freight forwarding system and international transport corridors. The new projects same as optimization need investments because corridor routes have a different direction vector depending on the profitability of national economies and companies, but their formation is based on a support network of transport and logistics centers in key nodes (points) of consolidation and distribution of cargo flows, and favorable conditions are created for investment projects.
 Due to the geographical location of Kazakhstan, the main transport routes connecting the States of the Asian and European continents pass through its territory and cargo transportation in interstate communication of the countries of the near and far abroad. They are carried out by rail and road transport in almost all main directions of the land road network. According to the UN classification, Kazakhstan, along with Russia, Azerbaijan, Georgia, and Turkey, is currently included in the transcontinental countries of interstate land communication. Therefore, it is very important for Kazakhstan to use its transit position to boost the economy and be a full-fledged participant in the global transport system.

Residual forest biomass and energy assessment: a case study analysis in the region of Alto Minho (North Portugal) for the creation of BLCs and 2GBLCs

ABSTRACT Recent synergies have increased the use of forest biomass for energy purposes. In addition to high investment costs, low feed-in tariffs, and low operational efficiency, the real potential of forest biomass does not always correspond to the potential that is often claimed in studies. Instead of total forest biomass assessments, it is recommended that sustainable afforestation criteria should be introduced to obtain more reliable and environmentally sustainable scenarios. In this article, the most representative forest species in the Alto Minho region (northern Portugal) are identified, as well as the total forest area available. Based on cartography, forest inventory data, and allometric equations, the annually available usable residual forest biomass (RFB) and corresponding potential energy are estimated. Finally, to promote local forest biomass markets and most efficient thermal use of forest biomass is suggested the creation biomass logistic centres (BLCs) and second-generation biomass logistic centres (2GBLCs) are introduced as well.

Construction Logistics Centres Proposing Kitting Service: Organization Analysis and Cost Mapping

The construction industry represents an important part of the global economy but is known for many issues such as harmful emissions, low productivity, waste generation, poor ergonomics, and construction incidents and accidents. A logistical view has proved to be a solid basis for improving construction performance while construction logistics centres (CLC) are gaining interest and proposing more services such as Kitting. Since the CLC-kitting-based approach is a new phenomenon, it is still a relatively unexplored topic. Hence, this paper addresses how this configuration could be applied to construction projects and what are its related costs information. The research design is based on a single case study showing the CLC-kitting use by a French general contractor in a student housing project. Data has been collected through site visits, observations, project documents, and discussions conducted with construction managers and logistics planners. Data analysis identified realized effects from deploying CLC-kitting in construction projects. Therefore, recommendations are provided, at both strategic and operational levels, which can be leveraged in similar projects. Finally, an identification of constructions logistics costs shows their distribution along the supply chain and was evaluated at 14.7% over material purchasing price.

Introducing Gamification in the AR-Enhanced Order Picking Process: A Proposed Approach

In the last decade, the Industry 4.0 concept has introduced automation and cyber-physical systems as the core elements of future logistics, supported by an array of technologies, such as augmented reality (AR) providing the necessary support for the digital transformation of manufacturing and logistics and the smartification and digital refinement of traditional pre-Industry 4.0 processes. This paper studies the influence and the potential of gamification techniques in supporting innovative Industry 4.0-enhanced processes in the contemporary warehouse work ecosystem. Gamification in the workplace aims to motivate the employees and increase their involvement in an activity, while at the same time creating a sense of an everyday different experience rather than a set of repetitive and monotonous tasks. Since the design of such a system is a complex process, the most widespread design frameworks are studied, and the emphasis is on the principal game elements and their connection to mobilization mechanisms. Finally, an initial proposal of a gamification framework to support the AR-enhanced order picking process in contemporary logistics centers is provided with an emphasis on the mechanics of a fair and functional reward system. The proposed approach aims to showcase the potential alignment of business processes to human motivation, respecting the differences between tasks and the workers’ cognitive workload.

Robustifying humanitarian relief systems against travel time uncertainty

AbstractWe consider a class of last mile distribution problems with multicenters and multiareas in disaster management, where the travel time for every pair of center‐area is uncertain. We propose a chance‐constrained model to handle this problem, which simultaneously determines the selection of emergency logistics centers (ELCs), the amount of relief transported to these ELCs, the allocation and routing of vehicles, and the equitable distribution of emergency materials from the ELCs to the disaster areas. We develop a distributionally robust optimization (DRO) model to reformulate the chance‐constraint model as a second‐order cone programming, which the proposed algorithm can solve efficiently. We present a case study of the Yushu earthquake in the Qinghai Province of the People's Republic of China to demonstrate the performance of our proposed model and method. The results reveal that (1) the DRO method outperforms the scenario‐based model in reducing cost and improving reliability, (2) deploying a large number of vehicles in the emergency centers near disaster areas can reduce cost, and (3) our proposed model evenly distributes vehicles on paths to curtail the rescue time.
