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

For adapting the socialization, individuation and servitization in manufacturing industry, a new manufacturing paradigm called social manufacturing has received a lot of attention. Social manufacturing can be seen as a network that enterprises with socialized resources self-organized into communities that provide personalized machining and service capabilities to customers. Since a community of social manufacturing has multiple enterprises and emphasizes on the importance of service, manufacturing service order allocation must be studied from the new perspective considering objectives on service cost and quality of service. The manufacturing service order allocation can be seen as a one-to-many game model with multi-objective. In this article, a Stackelberg game model is proposed to tackle the manufacturing service order allocation problem with considering the payoffs on cost and quality of service. Since this Stackelberg game can be mapped to a multi-objective bi-level programming, a modified multi-objective hierarchical Bird Swarm Algorithm is used to find the Nash equilibrium of the game. Finally, a case from a professional printing firm is analyzed to validate the proposed methodology and model. The objective of this research is to find the Nash equilibrium on the manufacturing service order allocation and provide strategies guidance for customer and small- and medium-sized enterprises with optimal service cost and lead time. According to the game process and Nash equilibrium, some rules are revealed, and they are useful for guiding practical production.

The study aimed to measure the effect of the Balanced Scorecard (BSC), with its four dimensions (financial, clients, internal operations, learning and growth) on reducing banking services costs in commercial banks in Palestine. The study used the descriptive, analytical, and also the regression analysis methods. The study depends on the questionnaire which was addressed, to (general manager, financial director, observer, head of accounting department). The study sample contained (47) employees working in commercial banks in Palestine. The study results showed a significant effect of using the Balanced Scorecard (BSC) and its four dimensions (financial, clients, internal operations, learning and growth) on reducing banking services costs in commercial banks in Palestine, The study recommended the necessity for commercial banks departments in Palestine to pay more attention to clarifying the importance of the Balanced Scorecard (BSC) method, which is one of the modern methods of accounting and its role in reducing banking services costs. And developing service cost plans using the Balanced Scorecard (BSC) and paying attention to all dimensions of the Balanced Scorecard for its role in reducing the costs of the services provided.

Corporate social responsibility (CSR) has become the focus of the company’s daily operations and strategic choices. At present, the supply risk events caused by the CSR violations of service providers in the service supply chain are frequent, which highlight the importance of formulating appropriate contracts to constrain the CSR level of providers. In the context of asymmetric CSR cost information, this paper analyzes the optimal contract parameters of integrators when providing screening contracts or pooling contracts and compares their impact on profits and the CSR level. The information asymmetry belongs to classic principal-agent problem, and we will use the revelation principle to design the contracts and solve this problem. The results that different contracts have different effects on the CSR level of different types of providers. A low-cost provider’s CSR level is the highest when a screening contract is provided, while a high-cost provider’s CSR level reaches the peak under a pooling contract. If pursuing profit maximization, the integrator should choose to provide a screening contract. When the integrator needs to ensure a higher average level of social responsibility, a pooling contract should be chosen. The findings also show that service cost is an important factor affecting the CSR level of the provider, and only when the providers’ service cost is low, will providers actively fulfill their social responsibility.

This article constructed a manufacturer-leading supply chain system considering the extended warranty service (EW) with a single manufacturer and a single retailer to study the influence of service cost on the choice of the EW provider. First, this article analyzed retail pricing, EW pricing, EW quality, the manufacturer's profit, the retail's profit and the total system profit in Model M and Model R. Then, the article analyzed the influence of service cost on the choice of the EW provider. Finally, it shows that if only part of consumers purchases the product with the EW, the manufacturer benefits from EW provided by the retailer. However, the retailer has to balance the ratio of the service cost coefficient. Furthermore, all consumers purchase the product with the EW, both the manufacturer and the retailer has to balance the ratio of service cost coefficient between manufacturer and retailer.

An efficient scheduling reduces the time required to process the jobs, and energy management decreases the service cost as well as increases the lifetime of a battery. A balanced trade-off between the energy consumed and processing time gives an ideal objective for scheduling jobs in data centers and battery based devices. An online multiprocessor scheduling multiprocessor with bounded speed (MBS) is proposed in this paper. The objective of MBS is to minimize the importance-based flow time plus energy (IbFt+E), wherein the jobs arrive over time and the job’s sizes are known only at completion time. Every processor can execute at a different speed, to reduce the energy consumption. MBS is using the tradition power function and bounded speed model. The functioning of MBS is evaluated by utilizing potential function analysis against an offline adversary. For processors m ≥ 2, MBS is O(1)-competitive. The working of a set of jobs is simulated to compare MBS with the best known non-clairvoyant scheduling. The comparative analysis shows that the MBS outperforms other algorithms. The competitiveness of MBS is the least to date.
