The purpose of this paper is to obtain insights into the typology uncertainty and relevant strategies adopted by manufacturing companies achieve better supply chain flexibility. Strategies are classified reactive (buffering) proactive (redesigning). We develop a framework that links uncertainty, two types for achieving flexibility objectives be achieved. Four case studies compared in terms being improve present three propositions as result study. First, flexibility, have been focusing more...

Cat swarm optimization (CSO) is one of the new heuristic algorithm which based on intelligence. Previous research shows that this has better performance compared to other algorithms: Particle (PSO) and weighted-PSO in cases function minimization. In a CSO for clustering problem proposed. The was tested four different datasets. modification made formula obtain results. Then, accuracy level poposed algorith those K-means PSO clustering. can improve comparison indicates be considered as...

In this paper, an important sampling method – Cross Entropy is presented to deal with solving support vector machines (SVM) problem for multiclass classification cases. The use of intended accelarate the process finding solution without sacrificing its quality. Using one-against-rest (OAR) and one-against-one (OAO) approaches, several binary SVM classifiers are constructed combined solve problems. For each classifier, cross entropy applied dual find optimal or at least near solution, in...

Downtime due to sudden machine failure will cause much loss the company.To overcome this, companies need develop suitable maintenance strategy.Nowadays, machines in smart manufacturing provide large volume data monitor conditions.Big analytics becomes needed for processing data, especially predicting Industry 4.0.Predictive works better than corrective or preventive maintenance.It can continuously diagnostic and prognostic processes predict future failures equipment's remaining useful life...

Scheduling is one of the most important processes in an industry both manufacturingand services. The scheduling process selecting resources to perform operation on tasks. Resources can be machines, peoples, tasks, jobs or operations.. selection optimum sequence from a permutation essential issue every research problem. Optimum becomes solution resolve problem NP-hard since number job more than normal processed by exact algorithm. In order obtain results, it needs method with capability solve...

Dynamic pricing is a strategy in which businesses set highly flexible prices for products or services based on current market demands. popular because of its ability to increase revenue company. For the scope Asia, China, Japan and Korea, are include three countries pioneered dynamic application electricity. There different programs well-known electricity includes Time Use (TOU), Critical Price Pricing (CPP) Real (RTP). Other Peak Rebate (PRT). Not just increasing revenue, can also be...

Rice is one of nine main commodities in Indonesia and it has been the food for Indonesian people over decades. Bureau Logistics (Bulog) a company under Government which responsible to manage distribution Commodity. Sourcing process Commodity most crucial Bulog. In spite importance process, sourcing was not maintained using any system at all. For such an important organization, manages product, rice commodity Bulog should be measured monitored. Supply chain processes, as have monitored order...

Although many efforts have been devoted to exploring dual sales channel (DSC) financial performance, the issue of managing its return is still lacking attention. Mismanagement in such online handling may threaten profitability. Therefore, we propose three scenarios. First, benchmark scenario a lost-sales consideration model. The second one an facility scenario, which represents availability provide product substitution. In accommodating customer preference through conventional store, store...

No-wait job-shop scheduling (NWJSS) problem is one of the classical problems that exist on many kinds industry with no-wait constraint, such as metal working, plastic, chemical, and food industries. Several methods have been proposed to solve this problem, both exact (i.e. integer programming) metaheuristic methods. Cross entropy (CE), a new metaheuristic, can be an alternative method NWJSS problem. This has used in combinatorial optimization, well multi-external optimization rare-event...

Climate change has significant impacts on changing precipitation patterns causing the variation of reservoir inflow. Nowadays, Indonesian hydrologist performs inflow prediction according to technical guideline Pd-T-25-2004-A. This does not consider climate variables directly, resulting in deviation observation results. research intends predict using statistical downscaling (SD) General Circulation Model (GCM) outputs. The GCM outputs are obtained from National Center for Environmental...
