Lack of appropriate warehouse ergonomics is one of the leading causes of worker injuries in industry environments. As management teams are trying to reduce the cost of doing business, they look to worker’s health statistics and realize they must improve their way of operating. The paper presents a warehouse analysis done at the request of the management team of a Belgian manufacturing plant. The factory’s warehouse was audited with focus on Kanban bin weight, storage rack height and rack width to assess the ergonomic strain it causes on workers. The paper then presents possible automation options in order to find the best fit to reduce ergonomic impact, while also optimizing the total investment cost.

There is a general consensus among scholars that the HR practices by corporate companies cannot be imitated by Small and Medium Enterprises (SMEs). Even though it is a neglected sector, SMEs in Tanzania are considered to be a major contributor to the national economy in terms of tax payment and job creation. Using a case study, this chapter investigates human resource practices in the recruitment process among the SMEs in a car maintenance sub sector. The nature of doing business is more informal, whereby a customer can bring a car to the garage and the technicians work on the car without bargaining for the cost of the work. Accordingly, there have usually been complaints from customers regarding over charging for the services offered and lack of trust among technicians, especially on matters relating to falsification on spare parts. In addressing this problem, garage owners have to make sure that they employ people with good character; those who cannot temper with customers’ property tarnish the image and reputation of the company.

Crises are an inevitable part of the life cycle of any organisation, regardless of its location, size, market, and sector. At the beginning of 2020, all organisations faced a new crisis caused by a COVID-19 pandemic. The rapid spread of the disease and its consequences to human health required a quick reaction of organisations to protect the health and safety of employees through physical distancing. Organisations had to reorganise their way of doing business and adapt to new circumstances. The first response to the crisis is to activate or form a crisis management team. The main goal of the crisis management team is to prepare the organisation for a new way of functioning by using all its opportunities and strengths to minimise the negative effects of the crisis. The success of crisis management and the recovery of an organisation depend on the quality of functioning of the crisis management team. The results of a survey conducted during April and May 2020 which included 108 members of crisis management teams showed that the respective teams responded adequately to the crisis caused by the COVID-19 pandemic. Research results showed that team members reacted quickly to the first signs of the crisis. They made real-time decisions by using a holistic approach due to their different knowledge, skills and experience, clear team roles, commitment to a common goal, open, honest and effective communication, and mutual trust.

AbstractA techno-economic study of a stand-alone PV water pumping system for water supply is done in this paper. An optimal design of the system is realized thanks to a double-objective optimization based on a proposed operational strategy of the system and on firefly algorithm (FA). The two objective functions simulated simultaneously using FA are: the function defining the cost of water (COW) and the function which defines the loss of water supply probability (LWSP). The system is designed to supply water to around 328 households in Cameroon, each composed by an average of six (06) persons. For different LWSP, the double-objective simulation determines the optimal configurations of the system with their related cost. The optimal and reliable (LWSP of 0%) system configuration obtained is composed by a number of 7 PV modules, a reservoir volume of 98.4 m3 with 2 days autonomy, a total dynamic head of 40 m, and a pump power of around 1 kW. The related COW corresponding to this configuration is 0.1185 $/m3, and the total investment cost is 27,506 $. The sensitivity analysis of the system revealed that the PV size, the volume of reservoir storage, and the efficiency of the pump influence the system both technically and economically, whereas the total dynamic head only influences the system economically. The validation of the optimized system has been done by comparison with manufacturer datasheets. It is demonstrated in this paper that the techno-economic analysis of energy systems based on multi-objective optimization using firefly algorithm is a powerful tool for decision-making.

Manufacturing systems need to be designed to cope with products’ variety and frequent changes in market requirements. Switching between product families in different production periods often requires reconfiguration of the manufacturing system with associated additional cost and interruption of production. A mixed integer linear programing (MILP) model is proposed to synthesize manufacturing systems based on the co-platforming methodology taking into consideration machine level changes including addition or removal of machine axes and changing setup as well as system level changes such as addition or removal of machines. The objective is to minimize the cost of change needed for transition between product families and production periods. An illustrative numerical example and an industrial case study from tier I automotive supplier are used for verification. Finally, the effect of maintaining a common core of machines in the manufacturing system on the total capital and change cost is investigated. It has been demonstrated that synthesizing manufacturing systems designed using the co-platforming strategy reduces the total investment cost including initial cost of machines and cost of reconfiguration.

In present work, an exergy based thermoeconomic optimization is applied to an actual cascade refrigeration system. The advantage of using exergy method of thermoeconomic optimization is that various elements of the system i.e. condenser, evaporator, compressor and cascade condenser can be optimized separately. A simplified cost minimization methodology based on thermoeconomic concept is applied to calculate the economic costs of all internal flows and products of the system by formulating thermoeconomic cost balance. Once these costs are determined, the system is thermoeconomically evaluated to identify the effects of the design variables on cost of the flows and products. This enables to suggest changes of the design variables that would make the overall system cost effective. Finally, an approximate optimum design configuration is obtained. The result shows that the increase in Coefficient of Performance and exergetic efficiency of the system by 13.76% and 16.20% respectively. The cost of the product and total investment cost are decreased by 19.71% and 19.18% respectively. This shows significant improvement in system performance as well as reduction in the cost of product and total investment cost. The reduction in cost and improvement in performance suggest the commercial acceptability of the cascade refrigeration system in a best efficient way.

In the article two types of rent are differentiated: resource rent and administrative rent. The latter is linked to restrictions on the access to the field of interactions. The contribution of the theory of public choice and the theory of rent-seeking and directly-unproductive activities is further developed by shifting the emphasis from individual decision-making to interactions between three actors: C, who controls access to the field, A, who gets a competitive edge as a result, and B, who assumes a subjacent position with regard to both A and C, yet still receives a positive gain from transacting. Domination by virtue of a constellation of As, Bs, and Cs interests is illustrated with the help of an in-depth case study of a Russian region. This study combines quantitative and qualitative methods, as well as their triangulation.

Shift to The Front II Komplek Sukamukti Banjaran Project is one of the projects implemented by one of the companies engaged in telecommunications. In its implementation, each project including Shift to The Front II Komplek Sukamukti Banjaran has a time limit specified in the contract. Project scheduling is an important role in predicting both the cost and time in a project. Every project should be able to complete the project before or just in the time specified in the contract. Delay in a project can be anticipated by accelerating the duration of completion by using the crashing method with the application of linear programming. Linear programming will help iteration in the calculation of crashing because if linear programming not used, iteration will be repeated. The objective function in this scheduling is to minimize the cost. This study aims to find a trade-off between the costs and the minimum time expected to complete this project. The acceleration of the duration of this study was carried out using the addition of 4 hours of overtime work, 3 hours of overtime work, 2 hours of overtime work, and 1 hour of overtime work. The normal time for this project is 35 days with a service fee of Rp. 52,335,690. From the results of the crashing analysis, the alternative chosen is to add 1 hour of overtime to 34 days with a total service cost of Rp. 52,375,492. This acceleration will affect the entire project because there are 33 different locations worked on Shift to The Front II and if all these locations can be accelerated then the duration of completion of the entire project will be effective

Abstract A component failure has the potential to significantly impact the cost, manufacturing schedule, and/or the perceived reliability of a system, especially if the root cause of the failure is not known. A failure analysis is often key to mitigating the effects of a componentlevel failure to a customer or a system; minimizing schedule slips, minimizing related accrued costs to the customer, and allowing for the completion of the system with confidence that the reliability of the product had not been compromised. This case study will show how a detailed and systemic failure analysis was able to determine the exact cause of failure of a multiplexer in a high-reliability system, which allowed the manufacturer to confidently proceed with production knowing that the failure was not a systemic issue, but rather that it was a random “one time” event.
