Abstract

Transportation planning is one of the important components to increase efficiency and effectiveness in the supply chain system. Good planning will give a saving in total cost of the supply chain. This paper develops the new VRP variants’, VRP with backhauls, multiple trips, and time window (VRPBMTTW) along with its problem solving techniques by using Ant Colony Optimization (ACO) and Sequential Insertion as initial solution algorithm. ACO is modified by adding the decoding process in order to determine the number of vehicles, total duration time, and range of duration time regardless of checking capacity constraint and time window. This algorithm is tested by using set of random data and verified as well as analyzed its parameter changing’s. The computational results for hypothetical data with 50% backhaul and mix time windows are reported.

Abstract

Stakeholder condition is particularly important to reach project success. The objective of this study is to investigate the stakeholder conditions which are suggested in three parts; stakeholder impact, stakeholder engagement, and stakeholder psychological empowerment on project success. The data obtained from a questionnaire survey administered to 197 respondents for initial research, 204 for main research, and 5 construction companies for validation research by using structural equation modeling (SEM) with program AMOS 16. The results indicated that stakeholder psychological empowerment applying of the ability to perform has a significant influence on project success measured by quality performance. On the other hand, stakeholder engagement reflected by engagement scope has no significant influence on project success

Abstract

This paper develops a vehicle routing problem (VRP) model for determining the routes in urea fertilizer distribution from a depot to retailers. The distribution is done in work days which uses trucks, each truck can serve more than one route (multiple trips), and each retailer has a time window. The vehicle routing model is built in a mixed integer linear programming (MILP) and the objective function is minimizing total transportation cost. The distances from the distributor to retailers and inter-retailers do not use Euclidian approach but the road network on a digital map in order to make the route solution is more realistic. Historical distribution data was used to test the model. The result shows that the model can minimize the cost about 2.28% which is compared to the original routes.

Abstract

This research aims at establishing model of multivariate time series by means of econometric instruments. Four instruments in use are vector auto regressive (VAR), structural vector auto regressive (SVAR), vector error correction model (VECM), and structural vector error correction (SVEC). VAR and VECM are employed to estimate and construct models and, subsequently, predict the future values of an object. SVAR and SVEC serve to analyze innovative structures of a model. VAR and SVAR can be implemented only to stationary data whilst VECM and SVEC can be applied to non-stationary inputs. The identification and estimation of the model in this research are specifically designed by R software. Based on this software, all the aforestated models are conclusively able to identify dynamic relationship of endogenous variabel in a model well.

Abstract

This study aims to investigate the impact of Tri Hita Karana culture toward entrepreneurial orientation and market orientation of SMEs of silver craft in Bali. The population of this research is all small and medium size enterprises of silver craft in Bali. By using purposive random sampling, 110 small and medium size enterprises located in four regencies in Bali were selected as samples. The data collection technique was distributing questionnaires. Furthermore, to test the inter-variabels influence, inferential analysis of Structural Equation Modeling (SEM) is applied using Partial Least Square (PLS) approach. The findings of this research are Tri Hita Karana culture could improve the entrepreneurial orientation and market orientation. It was also found that the entrepreneurial orientation influence the market orientation.

Abstract

The purpose of this research is to conduct an analysis on demand characteristic and inventory cost which might potentially influence the determination of base-stock level. Appropriate base-stock level will determine the maximum profit and also reduce the stockout cost for fashion products which has high demand uncertainty and single order problem. Case study is applied on a garment company with eight fashion product types that can be classified into short and long lifetime. The effect of coefficient variation, salvage price and stockout cost is analyzed towards profits and base stock level. It can be concluded that demand variability does not affect base stock level, while stockout cost and salvage price does.

Abstract

Integrated production-distribution problem resolution using analytical model lacks of consideration of many uncertainties along supply chain line such as delays, queues, machine breakdown, vehicle malfunction, and environmental factor. By utilizing simulation as complex stochastic system modelling, this research aims to develop hybrid analytical-simulation approach to resolve integrated production-distribution model. Time capacity adjustment is required if production-distribution plan obtained from analytical model requires longer production and delivery time than available. The adjustment is using a procedure developed based on duration obtained from simulation model and is used to obtain adjusted time capacity. The implementation of hybrid method to resolve integrated production-distribution problem on two echelon supply chain with 2 factories and 5 DCs shows a feasible solution was obtained on the third iteration
