Abstract

XYZ is a pasteurization milk processing company that produce milk drink from pure cow milk. PT. XYZ don’t sell their product directly to end user, instead they distribute their product to many companies which serve milk for their employees or operators in lunch time. So, their customer is mostly a manufacture company from various kinds of industry. They have about 40 customers and most of them are outside Bandung. However, the delivery may not be done as planned. The average on time delivery is around 96%. it is below PT. XYZ target which is 98%. The impact of the delay itself is vary between customers. Because when delay occur, each customer has their own regulation that has been settled in agreement contract. Based on the delay recapitulation above, there are several factors that caused this problem. Delay in departure is the most influential factors. It is because PT. XYZ don’t have fixed schedule of delivery and they miscalculate the departure time because of improper route determination that also leads to longer travel time. This case is categorized as Vehicle Routing Problem with Heterogeneous Fleet and Time Window (VRPHFTW) that will be solved using one of meta-heuristics algorithm which is Two Phase Tabu Search Algorithm to minimize travel distance. In the end, the travel distance can be minimized 19.48%. Keywords—Vehicle Routing Problem with Heterogenous Fleet and Time Window (VRPHFTW), Meta-Heuristics, Two Phase Tabu Search Algorithm.

Abstract

The rapid development of technology has shifted the conventional tourism industry towards the digitalization of the tourism sector. The emergence of travel booking platforms, as a form of technology-based service innovation, is able to simplify traveling activities and previous works of literature have indicated a positive relationship towards customer satisfaction. However, tourist's behavior has change become more demanding to involve in the creation of value in accordance with their needs and wants. The concept of value co-creation elaborates this issue, offering a new concept of value creation and new roles between service providers and tourists. This study aims to examine value co-creation as mediating variable between IT-based service innovation and customer satisfaction, using DART measurements and SEM-PLS is used to assess the model. The findings prove that IT-based service innovation positively influences value co-creation between users, which can increase customer satisfaction. However, IT-based service innovation does not have a direct impact on customer satisfaction, which indicates that value co-creation fully mediating the relationship between service innovation and customer satisfaction. Thus to enhance customer satisfaction, service providers need to propose service innovation that facilitates customer involvement in value creation, which can be supported by technology. Keywords: Customer satisfaction, Service innovation, Tourism, Travel booking platform, Value co-creation.
