In 1996, GS E&C became the first in the industry to adopt a Project Management System using EVM(Earned Value Management) to link schedule with profit/loss. In 2006, the TPMS(Total Project Management System) was completed by adding the concept of Lean Construction and JIT(Just In Time) to the Project Management System. This was done with the purpose of reducing waste and creating optimal work processes. This has been implemented on all sites and has enabled drastic increase of productivity. The portal provides customized information to the client, inspector and subcontractor personnel. Since various parties are receiving information that suits their requirements and is easy to use, usage has increased and since they are on the same platform, quick decisions and information sharing is possible. The purpose of the PMIS's success model in construction projects, this paper tests and proves the TPMS's efficiency and productivity to Dongnam Distribution Complex project.

The aim of this study is to consider the physical distribution system of assembly supplied from $1^{st}$ supplier and module corporation to automobile assembly plant through analysis of existing literatures and interview survey. The major findings of this study are as follows. Parts supply of automobile are to bind together with many regional parts supplier than using multi frequency and small delivery of JIT. Regional physical distribution center of joint parts and integrated physical distribution information center is to be installed in neighboring region of automobile assembly plant in order to reduce the transport cost by designating and activating multiple physical distribution and transport companies in each automobile assembly plant and turning into effective high volume shipping system.

생산시스템에 대한 연구는 주로 hybrid 생산 시스템 효율성의 우위를 비교적 단순한 생산환경에서 부각시키는데 초점이 맞추어져 왔다. 본 연구에서는 실제 생산 환경에 근접한 모형을 세우고 MRP생산 시스템과 JIT 생산 시스템을 통합하는데 있어서 고려할 요소로서 기존의 MRP에 의한 간반의 자동 생성 이외의 다기능 작업자와 간반의 우선순위의 추가 요소를 고려하였다. 본 실험에서는 유휴한 상태의 다기능 작업자를 이를 필요로 하는 work centers로 배치하는 법칙을 도출하였고 간반의 우선순위를 부여함으로써 보다 재고 수준을 줄여 제품의 흐름생산에 가깝도록 하였다. 위 실험은 카메라 제조업체를 대상으로 모의실험은 Arena를 이용하였다.

Goldratt박사에 의해 제창된 TOC(Theory of Constraints)는 제약조건을 찾아 개선시켜 없애고 시스템 심과를 높일 수 있는 방안을 찾는 제약이론이다. 생산공정을 포함한 모든 분야에서 제약이란 없을 수가 없다. 따라서 기존의 MRP나 PERT/CPM과 같은 무한 자원 스케줄링으로는 예상하지 못한 문제가 도출될 수 밖에 없는 한계를 제약공정의 자원능력이 유한하다는 가정에서 출발하는 제약이론으로 자원활용의 최적화를 도모할 수 있다. 본 논문에서는 TOC와 많은 유사점을 가지고 있는 생산시스템인 JIT와 비교하여 아직 국내에는 활발한 연구가 이루어지고 있지 않은 TOC를 기반으로 최적 생산시스템을 연구하고자 한다.

간판시스템의 목적은 최소한의 자원으로 수요에 대처하고, 궁극적으로 생산리드타임을 단축하여 제품생산원가를 줄여 대외적인 경쟁력을 확보하는 데 있다. 간판생산시스템은 수요에 따라 생산하여 최소한의 재고를 보유하고 공급하기 때문에 다품종 소량생산에 매우 적합하다. 그러나 간판시스템을 도입하는 데에는 생산시스템에 많은 조건들이 전제가 되어야 한다. 그리고 간판시스템은 JIT 생산시스템을 이루는 하부구조가 안정적인 상태를 유지할 때 성공적인 도입이 가능하다. 본 논문에서 우리나라 기업, 특히 중소기업에서의 간판시스템 도입 시에 성공적인 도입을 위해 고려해야 할 사항과 절차 등 표준모델을 제공하는데 있다.

Applying JIT(Just-In-Time) production system to strength competitiveness power and renovate managent has problems. This study is proposed to solve one of the problems, that mother company has different production system with subcontractor, in order to connect production system of mother company with subcontractor. In the view of the Pull System, production system of mother company, it is possible that the more smoothed production planning is established by developing the algorithm the smoothed production planning preserving the LOTproduction system and comparing the existing research. Also, in the view of subcontractor taking Push System, the possibility of keeping delivery and improving productivity is proved using simulation technique by changing Job shop to GT Cell production system because demand is fluctuating.

By successful establishment of Supply Chain Management System they should make the supply chains speedy and combine production information system with the outcome system and thus they reinforce the competition of the production system of local enterprises in accordance with the rapid decision making. Supply chain coordination improves if all supplier of chain take actions that together increase total supply chain profits. To design of Modularity by the grouping supplier, the proposed method is to develop the most appropriate production system models through the reflection of JIT system in the Supply Chain Management which is necessity of the times and its importance. The objects of this study is to develop the most appropriate production system Model and optimal profit model in the process line and to provide the enterprises with the models which are based on the Supply Chain Management.

Traditional Manufacturing method is push system by plan made in advance and Japanese manufacturing method represented by JUST-IN-TIME is pull system which respond's to the demand flexibly. Both have their pros and cons. In general, it is well understood that push system is faster than pull system in the sense of manufacturing speed. However, pull system such as JIT excelles dramatically in the sense of work in process. Therefore, this paper is trying to put together to get alternative which has the advantage of both system. The objective of the paper is to enhance the effect of built-in manufacturing system without paying extra cost by way of introducing the alternative of the pull-push manufacturing strategic operational method.
