A win-win supply chain solution using project contracts with bargaining games

For product supply chains, contractual relationships that provide win-win outcomes between the supply chain members, have been found to offer optimum results. However, for bargaining situations where time/cost is the source of the uncertainty, i.e. projects, there is limited knowledge available on how contracts can be used to establish win-win relations. This paper investigates whether cost-sharing project contracts can establish a win-win solution in project supply chains where the project manager is risk-neutral and the contractor is risk-averse. The paper examines how the theory can be extended beyond the symmetrical normal distributions to asymmetrical beta and gamma distributions that are more appropriate, and so more often used, for project completion times. Besides using the Nash bargaining approach for analyzing the bargaining process, the paper also analyzes the bargaining problems using the Kalai-Smorodinsky and Utilitarian approaches to bargaining. It was found that the solutions from cost-plus contracts dominate any other form of cost-sharing contract, and so they provide a win-win solution for both members of the supply chain for the cases of Nash and Kalai-Smorodinsky bargaining. However, this is not the case for Utilitarian bargaining. A numerical exercise was conducted to investigate the results and implications of how the models would work in practice. The research shows that from a theoretical perspective, cost-plus contracts are the optimal bargaining solution not only when using a normal distribution, but also when using more appropriate asymmetrical distributions. This optimality is robust for the Nash and Kalai-Smorodinsky bargaining approaches, but not for the Utilitarian approach whose sensitivity to noise makes it an inappropriate choice here

Centre for Non-destructive Evaluation at CSIR-National Metallurgical Laboratory, Jamshedpur for materials characterisation and damage evaluation: an Overview

Non-Destructive Evaluation (NDE) centre established in 2003, with a partial funding from Department of Science & Technology (DST), Govt. of India at CSIR- National Metallurgical Laboratory, Jamshedpur has developed different NDE based methodologies for characterisation of microstructure and assessment of different kinds of damage (creep, fatigue, corrosion etc) for diverse components from aerospace, defence, power and steel sector. Besides, need based development of NDE sensors and techniques for specialised applications are also the integral part of Centre activities. This paper will highlight some of the above activities particularly the research activities on fatigue and corrosion damage evaluation in structural materials by advanced NDE

Non-destructive Testing and Evaluation at CSIR-National Metallurgical Laboratory, Jamshedpur for Iron and Steel Industry: an Overview

In the area of iron and steel, the NDE centre at CSIR- National Metallurgical Laboratory has not only developed different NDE based methodologies for characterisation of microstructure and assessment of different kinds of damage (creep, fatigue, corrosion etc) in various grades of steel; but also developing methodologies for blast furnace lining thickness measurement and assessment of High Speed Steel (HSS) rolls. This paper will highlight some of the above activities particularly related to steel and allied industries

Feasibility of using ultrasonic technique to measure the blast furnace lining thickness

Blast furnace process has been the most effective way to produce iron for over 200 years.Throughout the years, large efforts have been put on finding ways to increase the productivity and extend the campaign length. The condition of the refractory lining of a blast furnace plays a very important role to determine its campaign length. Many methods have been employed to measure blast furnace lining thickness including radioisotopes, thermal measurement and core-drilling. Temperature measurement is among the most widely used method for on-line monitoring the profile of the blast furnace inner surface, which is based on numerically solving inverse problem using heat transfer models and readings from thermocouple. Optimization methods are applied to obtain the boundary of the domain iteratively, and hence the computation is very expensive and calculation cannot be very accurate. This paper presents the feasibility of using non-invasive ultrasonic technique in bistatic mode to measure the profile of the refractory liner of the hearth region of blast furnace

Catch tank inhibitor addition 200-East and 200-West Areas

Reported is the study of 11 catch tanks in the 200-East Area and the 7 catch tanks in the 200-West Area listed as active. The location, capacity, material of construction, annual total accumulation, annual rain intrusion, waste transfer rate, and access for chemical injection in these tanks are documented. The present and future utilization and isolation plans for the catch tanks are established

Eksplorasi Pemanfaatan Docker Untuk Mempermudah Pengelolaan Instalasi Komputer Di Laboratorium Komputer Teknik Informatika Universitas Kristen Petra

Docker is an application that is based on open source technology that allows developers or anyone to create, run, do experiments and launch application in a container. Docker make the process of packaging application components together quickly in an isolated container, so it can run in local infrastructure without changing configuration on the container. Docker also very light and fast when compared to hypervisor-based virtual machine.Department of Information Engineering of Petra Christian University has a considerable number of students, which the number usually hundreds, while the number of computers in the laboratory of Department of Information number is not as much as the students. With this amount is not comparable, then some students work in the same computer alternately. It makes the students cannot be comfortable working on one computer, because configuring a computer on every lesson is different. Therefore, implementation of Docker application carried out in the laboratory.Docker implementation and RAID storage system and after implementation, testing was done by measuring the speed of docker image transfer. The resulting data were used to development of container system and evaluate the speed of RAID storage system are used
