Although companies have to concentrate on effort to save cost to survive competition, transportation costs are taking more portions in total sales costs due to globalization in the modern times. It is the reason why Transportation Management System TMS is getting more important. However, it is practically difficult for the system to fit to all of transportation environments and actually many problems are taking place with the system. Therefore, a new idea is necessary to solve such problems fundamentally rather than temporarily or superficially. To do so, if TRIZ, which is a theory that systematically establishes creative ideas on the basis of patent analysis, is employed, it can bring forth a guideline with some creative principles that can be applicable in drawing out innovative ideas based on conceptual shift. The present study aims to propose a methodology of how TRIZ should be applied to solve the problems that happen in TMS as a whole. Particularly, the study focuses on how to design customized TMS system that can be employed for each of different situations in a creative way.

A cell site lease is a legal agreement by which the owner of a building or a piece of land allows a wireless carrier to use part of it for a cell tower for a period of time in return for money. Wireless carriers spend significant money for cell site leases. This paper tries to find factors affecting cell site leases and management solutions to save lease costs. In other words, this research identifies any factor influencing cell site leases among age, gender, and geographical area in the first problem and determines management priorities using an importance-satisfaction model in the second problem. This paper can provide wireless carriers with effective decision making tools and a basis for negotiation of cell site leases, as they do not have enough bases for negotiation.

In real world, the project managers handle conflicting goals that govern the use of resources within the stipulated time and budget with required quality and safety. These conflicting goals are required to be optimized simultaneously by the project managers in the framework of fuzzy aspiration levels. The fuzzy linear programming model proposed herein helps project managers to minimize total project costs, completion time, and crashing costs considering indirect costs, contractual penalty costs etc by practically charging them in terms of direct cost of the project. A case study of bituminous pavement under construction is considered to demonstrate the feasibility of applying the proposed model for optimization of project parameters. Consequently, the proposed model yields an efficient compromise solution and the decision maker's overall degree of satisfaction with multiple fuzzy goal values. Additionally, the proposed model provides a systematic decision-making framework, enabling decision maker to interactively modify the fuzzy data and model parameters until a satisfactory solution is obtained. The significant characteristics that differentiate the proposed model with other models include, flexible decision-making process, multiple objective functions, and wide-ranging decision information.

Full embroidery industrial accidents in recent years has shown a declining trend. But disaster embroidery of domestic construction industry were more than 20,000 deaths per year is about 500 people. The government has introduced a construction site often changing the recruitment of new construction based on health and safety as an alternative to road safety education training yisuje of construction workers, daily work periods short. Certificate of Basic OSH Training in Constructions had also been evaluated as successful by reducing the accident rate problem. It is conducted in private educational institutions has occurred on the friction between workers and employers and training costs are difficult to approach workers in the education standards for such facilities due to the superintendent. Educational institutions are institutions that have been caused by excessive competition lowered levels of education. There is also a lack of evaluation that the training is limited to the basic safety knowledge. These details are brought formal safety education purposes only and is introducing the results of other self jyeotgi difficult to reap the proceeds to good effect. In this study, we propose a plan for improving operational problems and enemy status based on research data presented after the Certificate of Basic OSH Training in Construction.

The railroad system must ensure not only the safety of facilities but also the prevention of natural and environmental disasters. The infrastructure must be strengthened in order to prevent rail damage by natural disasters and other causes. Thus, it would be able to prevent damage due to such natural factors like heavy rain and snow fall, wind, and catastrophic earthquakes. It seems that it would be the best way to install safety facilities throughout the entire length of a route, but one would not be able to provide for the costs involved in this approach. Therefore, these facilities must be installed at selected locations that is the most vulnerable to disasters. In this paper we propose the examples of both foreign and domestic methods in order to prevent from damages caused by the above-mentioned natural disasters and others.

IPS(Ideal Production System) is a strategic cost management establishing ideal target cost, innovating cost structure and reduction. However, IPS was commonly used in assembly industry acquiring components and using them to assemble vehicles etc. Applying IPS to steel industry is a new try and not easy because cost elements in flow manufacturing are clustered and obfuscated in a complicated way. This paper proposes ICM (Ideal Cost Management) method adaptive to steel industry. One of the biggest advantages is that ICM could classify and categorize costs in detail according to accounts and manufacturing machines. Based on ICM information, steps of extracting and maximizing ideas are followed effectively. From 2013, ICM was applied successfully to POSCO Pohang Steel Works 38 factories.
