The estimation of production rate (or throughput) is important in manufacturing system design. Herein, we consider the an automotive body shop which two types car are produced, and one (engine car) substituted by other (electric gradually. In this shop, different underbody lines installed because structures cars differ completely; however, side line main shared cars. Furthermore, assume that re...

In stored grains, smaller depositions and great variations with regard to theoretical insecticide doses are frequently found. The objective of this work was to evaluate the influence of the emulsifiable concentrate formulation on the physical properties of the liquid, volumetric distribution, droplet spectrum, and insecticide deposits on stored grains. To determine its physical properties, the ...

Prior to a new product launch, marketers need to infer how demand will respond to various levels of marketing mix variables in order to set an appropriate marketing plan. A critical challenge in estimating marketing mix responsiveness from historical data is that the observed decisions were affected by private information possessed by managers about the heterogeneous effects of marketing mix va...

The quality of hot mix asphalt is affected by the quality and consistency of input aggregates and the control of the production process. To improve the quality of hot mix asphalt, both the aggregates gradation and the process variables must be considered. Current practice involves taking samples from actual production and analyzing them in the lab. The entire process can take two hours, which, ...

This article studies optimal investment in flexible manufacturing capacity as a function of product prices (margins), investment costs and multivariate demand uncertainty. We consider a two-product firm that has the option to invest in product-dedicated resources and/or in a flexible resource that can produce either product, but has to make its investment decision before demands are observed. T...

Pasar elektronik (e-marketplace) memberikan paradigma baru bagi setiap organisasi bisnis dalam mengelola usahanya, termasuk UMKM pangan. Identifikasi perubahan yang diperlukan pada traditional marketing mix (4P) menjadi kebutuhan untuk membangun model sesuai relationship di e-marketplace. Penelitian ini bertujuan mengetahui pengaruh e-marketing (product, price, place, promotion) terhadap tingka...

Association rules is a recent data mining technique to discover affinities, in large transaction databases, between items frequently purchased together. It has been claimed that the discovery of frequent sets of items is well suited for applications of market basket analysis to discover regularities in the purchase behaviour of customers. In this study, we integrate the discovery of frequent it...

The optimal product design problem, where the ‘‘best’’ mix of product features are formulated into an ideal offering, is formulated using ant colony optimization (ACO). Here, algorithms based on the behavior of social insects are applied to a consumer decision model designed to guide new product decisions and to allow planning and evaluation of product offering scenarios. ACO heuristics are eff...
