<![CDATA[Scheduling is an important area of production planning and control. Scheduling is required to produce an existing job by allocating existing resources in the proper execution order. Production schedules arranged effectively and efficiently to maximize resources utility, minimize waiting and idle time and increase productivity. The flowshop batch scheduling model for one machine that takes inventory and quality cost into account has been developed by Indrapriyatna et al (2007a). However, the model yet effective in converting the results of batch size into integers. This study tried to resolve this problem by using a modification of Branch and Bound Algorithm approach. ]]>

<![CDATA[Inventory is one of many factors of the business operation that need to be controlled by industries in order to improve efficiency, enhance productivity, and decrease the holding cost. The holding cost of inventories in supply chain contribute to 20% - 40% of the product value. It can be controlled by applying appropriate inventory model, such as EPQ/Economic Production Quantity and EOQ/Economic Order Quantity. EPQ is an inventory model that used to determine the optimum production lot size with balanced the production setup cost and holding cost. Even the classic EPQ has applied widely in industries, the assumption used by this model differed between the researchers whether it is continuous or discrete demand, because the multi delivery or discrete demand is mostly used by industries. Even so, there are industries that used both continuous and discrete demand simultaneously. Based on previous research, there was an advanced EPQ model that synchronizing both assumptions simultaneously, but it still addressed single item problem. Since almost the industries produced multi item, this model has lack of applicability. Therefore, this research proposed a multi item EPQ Model that synchronizing continuous and discrete demand simultaneously. The solution procedure that used in this proposed model are classical calculus method/differential calculus and simultaneous approach. A numerical example is given to show the effectiveness of the proposed approach based on the data from the literature.]]>

<![CDATA[One of the factors to increase the competitiveness is the price of product. One of the factors that affect the product price is inventory cost. Shortages inventory can result in the cessation of the production process so that inventory is one of crucial issue in the company's operation while overstock had an effect on high costs. This research aimed to obtain integrated inventory model between products and packaging materials to minimize the total cost of inventory at PT Indomex Dwijaya Lestari considering safety stock. Data used in this research are the major and minor setup cost, production cost (one cardboard products) , sales data of mineral water for cup and bottle products from January 2011-April 2013 , data of production bottle mineral water for cup and bottle products from January 2011-April 2013, and the price of packaging materials . Then, data is processed to obtain the minimum inventory cost by using a phased approach and the simultaneous approach (using the software LINGO 11.0) for inventory model that considers safety stock and inventory model without considering the safety stock.Results of this research obtained an integrated inventory model between products and packaging materials that considering safety stock and without considering safety stock in PT Indomex Dwijaya Lestari. Based on the calculation, the result is valid. The proposed inventory costs are cheaper than the company's current inventory costs. The cost of the company's current inventory is Rp. 15.020.370,09 considering safety stock per month . Inventory costs in the company without considering safety stock is Rp 13.651.301,74 per month. The cost of inventory using gradual approach is Rp. 4.328.441,38 per month considering safety stock and Rp. 2.745.085,15 per month without considering safety stock. The cost of inventory using the simultaneous approach is Rp. 3.543.637,00 per month considering safety stock and Rp. 3.543.637,00 per month without considering safety stock.]]>

<![CDATA[Penelitian ini bertujuan untuk memberikan usulan peningkatan kualitas pelayanan pada salah satu Badan Usaha Milik Negara (BUMN) di Kota Batam yaitu PT.XYZ, khususnya pada unit usaha pergudangannya yang mengalami tren penurunan permintaan melalui pendekatan integrasi metode Servqual dan Kano. Data diperoleh dari konsumen tetap PT. XYZ, kemudian dilakukan pengukuran dan analisis terhadap atribut dimensi Servqual dan kategori model Kano. Hasil penelitian ini adalah semua atribut pelayanan memiliki gap skor negatif pada analisa Metode Servqual sehingga termasuk kategori kualitas pelayanan yang lemah dan perlu untuk ditingkatkan. Selanjutnya dilakukan analisa model Kano pada semua atribut yang memiliki gap skor negatif dimana hasilnya hanya muncul 2 (dua) kategori yaitu Must Be dan One Dimensional. Berdasarkan evaluation rule model Kano, atribut yang termasuk kategori Must Be perlu diprioritaskan untuk ditingkatkan karena kategori tersebut sudah semestinya dipenuhi perusahaan. Adapun kelima atribut tersebut yaitu, perusahaan memiliki peralatan dan teknologi terbaru (modern), material dan fasilitas fisik lain yang terkait layanan perusahaan tampak menarik, karyawan perusahaan memberitahu pelanggan kapan pastinya layanan akan disampaikan, karyawan perusahaan selalu bersedia membantu para pelanggan dan perusahaan selalu memperhatikan kepentingan pelanggannya]]>
