Abstract

The purpose of this study is to increase the price competitiveness of regional small and medium-sized shipbuilding industry by introducing adequate supply chain management model concept for small and medium-sized shipbuilding yard. In a today's highly competitive face the challenge of reducing manufacturing cycle time, delivery lead-time and inventory reduction for the production of small and medium-sized vessels, medium-sized shipyards heavily depend on outsourcing organizations and many organizations involve for manufacturing vessels accordingly. Every organization has its own objectives and its own way of decision-making processes. Due to the conflictions among the objectives of each organization and non-integrated decision-making processes, there has been a need for a new mechanism, which helps to resolve those conflictions and to integrate processes.[1] In the early 1990s, the phrase “supply chain management” came into use. Supply chain management is a process of integrating/utilizing suppliers, manufacturers, warehouses, and retailers, so that goods are produced and delivered at the right quantities, and at the right time, while minimizing costs as well as satisfying customer requirements.[1] ERP can be defined, as a software solution that addresses enterprise needs to meet the organizational goals (including manufacturing goals) of an enterprise tightly integrating all functions of an enterprise.[1] The SCM system apply advanced technologies to achieve improved plans that take into account most of the factors and constraints that limit the ability to deliver on time. The leading edge SCM system are able to consider all the relevant constraints in the procurement, manufacturing, distribution, transportation and warehousing operations simultaneously, and to perform real-time simulations of adjustments in the constraints.[1] It is quite clear that for small and medium-sized shipyard, which heavily depends on outsourcing companies need efficient SCM system. Expected benefits of supply chain management for small and medium-sized shipyards can be described as follows. 1) Throughput improvements: Better coordination of material and capacity prevents loss of utilization waiting for parts. 2) Cycle time reduction: By considering constraints as well as its alternatives in the supply chain, it helps to reduce cycle time. 3) Inventory cost reductions: Demand and supply visibility lowers the requirement of inventory levels against uncertainly. Ability to know when to buy materials based on the customer demand, logistics, capacity and other materials needed to build together. 4) Optimized transportation: By optimizing logistics and vehicles loads. 5) Increase order fill rate: Real-time visibility across the supply chain (alternate routings, alternate capacity) enables to increase order fill rate. 6) Analysis of the supply chain management can help to predict propagation of disturbance to downstream. 7) Increase customer responsiveness: Understanding the capability to deliver based on availability of materials, capacity and logistics.[1] Ordinarily in the view point of operation power on supply chain management, small and medium-sized shipbuilding industries should have uni-centric supply chain management. Therefore, this research proposes three supply chain management models which are designed for small and medium-sized shipbuilding yard. The first is the polycentric supply chain model for federated small and medium-sized shipbuilding enterprise. The second is multiple supply chain management models that divide overall supply chain into several chains according to each domain. The third is the competition management model based on internal partnering among members which are participated in a same supply chain management organization. And from a political approach perspective of local autonomous entity or central government, this research provides some policy proposal to install and set up the improved supply chain management for small and medium-sized shipbuilding industry newly.
