This paper presents an economic production quantity (EPQ) model with a periodic order quantity (POQ) policy, product reliability and periodic demand. The machine reliability has decreased over time; therefore, the rates of perfect and defective products reduce and increase over time, respectively. A fixed percentage of these products are reworked while the rest is wasted. Some equipment in thei...

This paper considers component supply planning for assembly systems where several types of components are needed to produce one finished product. The actual component lead times have random deviations. The aim of this study is to find the optimal MRP offsetting when the Periodic Order Quantity (POQ) policy is used. The proposed model and algorithms minimize the sum of the setup and average hold...

This study aims to find out how control raw material inventory which is traditionally carried by the Tempeh Soybean Factory analyzing using Economic Order Quantity (EOQ) and Periodic (POQ) methods. In this study, we uses a descriptive-qualitative approach. The author observation, interviews, documentation in collecting data. resource persons consisted of factory owners, assistants, employees at...

Following Henkin’s discovery of partially-ordered (branching) quantification (POQ) with standard quantifiers in 1959, philosophers of language have attempted to extend his definition to POQ with generalized quantifiers. In this paper I propose a general definition of POQ with 1-place generalized quantifiers of the simplest kind: namely, predicative, or “cardinality” quantifiers, e.g., “most”, “...

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 me...

Bahan baku menjadi suatu hal yang sangat penting dalam melakukan produksi karena jika bahan kekurangan akan mengakibatkan terhentinya ataupun kelebihan bertambahnya biaya penyimpanan. Tujuan dari penelitian ini adalah untuk mengetahui total jumlah persediaan menggunakan metode EOQ (Economic Order Quantity) dan POQ (Period serta membuat skenario perencanaan perusahaan. Sebelumnya perusahaan peme...

The Phobic Origins Questionnaire (POQ) [Ost, L.-G. & Hugdahl, K. (1981). Acquisition of phobias and anxiety response patterns in clinical patients. Behaviour Research and Therapy, 19, 439-447.] is the most commonly cited instrument for determining the origins of phobic anxiety and data obtained using this instrument strongly support the role of conditioning in the acquisition of fear reactions....
