ANALISIS PERENCANAAN PERSEDIAAN MATERIAL PROYEK DENGAN METODE MATERIAL REQUIREMENT PLANNING (MRP)

نویسندگان

چکیده

Kekosongan persediaan material pada saat pelaksanaan proyek dapat mengakibatkan penyelesaian suatu pekerjaan menjadi terhambat sehingga akan mempengaruhi total waktu serta biaya proyek. Apabila terlalu banyak maka membutuhkan ruang penyimpanan dan terjadi penyusutan yang berdampak meningkatkan biaya. Untuk menghindari hal tersebut perlu dibuat perencanaan efektif efisien dengan mempergunakan metode Material Requirement Planning (MRP). Pada penelitian ini objek diambil adalah pembangunan Gedung G RSUD Mangusada. Metode MRP tersusun dari 4 langkah mendasar yaitu explosion, netting, lotting, offsetting. bagian lotting digunakan teknik lot size Lot for (L4L), Economic Order Quantity (EOQ), Period (POQ), Part Balancing (PPB). Hasil analisa menunjukkan bahwa sizing minimum PPB. Biaya beberapa jenis lainnya juga diketahui POQ floordeck 0,75 mm, besi tulangan Ø10, D10, D13, D22, wiremesh M10. Total untuk plywood 9 mm Rp. 287.881.419,84; kayu meranti 5/7 751.779.089; 6/12 322.666.416; Ø10 Rp.439.697.676; D10 7.331.078; D13 Rp.9.064.629; D16 161.894.134; D19 398.662.264; D22 331.879.350; 178.601.663; M10 234.037.572; M8 351.353.969; beton ready mix K-300 1.412.180.000; K-250 37.267.500; scaffolding 480.000.000.

Focusing material requirements planning (MRP) towards performance

This paper looks at the successes and disappointments of MRP. It studies numerous articles to determine what the key shortcomings of MRP are. Next, it investigates if these failures are correctable, and what the consequences of not correcting these de®ciencies means. This article considers alternatives that have been discussed in the current literature. Last of all this article discusses whethe...

Material Requirement Planning under Fuzzy Lead Times

This paper proposes a fuzzy multi-objective integer linear programming approach to model a material requirement planning (MRP) problem with fuzzy lead times. We incorporate to the crisp MRP model the possibility of occurrence of each one of the possible lead times. Then, an objective function that maximizes the possibility of occurrence of the lead times is considered. By combining this objecti...

Material Requirement Planning with fuzzy constraints and fuzzy coefficients

Wepropose a new fuzzymathematical programmingmodel for production planning under uncertainty in an industrial environment. This model considers fuzzy constraints related to the total costs, the market demand and the available capacity of the productive resources and fuzzy coefficients for the costs due to the backlog of demand and for the required capacity. The main goal is to determine the mas...

Supply chain master planning considering material-financial flows

In this study, tactical decisions considering the material and financial flows in a supply chain have been made. To achieve these aims and some effective solutions, a multi-objective mathematical model proposed for an integrated supply chain master planning problem. The multi-product, multi-period and capacitated supply chain network has three objective functions. Two first objective functions ...

Net Change Material Requirements Planning

Defined and evaluated are concepts and characteristics of net change, a method that facilitates replanning and provides timely response to chunge in a transaction-oriented system. (MRP) entail an inherent massive data-handling task. Consequently , batch-oriented MRP systems tend to be untimely in their response to change since replanning can be done only periodically at best, probably once a we...
