Two open source distributed machine learning/deep learning platforms, namely H2O and Apache SINGA, compared their deep learning performances using multilayer perceptron on the classic MNIST database for hand written digits recognition. However, the results reported by both parties differ and neither of them can repeat the results reported by the other side. This paper is an independent study of the...
In the maritime supply chain, sailing speed is a key variable governing ship-to-air emissions and the profitability of vessels. While there can be substantial economic gains to be had from dynamic speed optimization, real-life constraints such as weather conditions, contractual limitations and supply chain considerations may govern the speed choice in practice. The increasing availability of high-frequency...
This paper propose an improved MIP formulation to reach the objective of Unequal area facility layout problems (FLP) that is to minimize the total material handling cost. Facility layout problem is defined as locating departments in facility with a given dimension, and the departments can't overlap. The FLP can be formulated as a mixed-integer programming (MIP). In past researches, many researchers...
With high consideration of sustainability, product recovery has become a major interest of product manufacturers by retrieving obsolete products. Disassembly processes can make an impact on the product recovery and be necessary to develop sustainable product design by achieving the product recovery strategy. Therefore, this paper proposes a method to assess product disassembly complexity that represents...
This paper attempts to provide a conceptual framework on factors that affect the purchasing performance of Engineering, Procurement and Construction (EPC) companies'. Till date purchasing performance models have been published for manufacturing firms, this study fills the gap by investigating the factors that constitute Purchasing Performance of an EPC. To accomplish present research objective, an...
Setting an optimal inspection plan for fatigue critical offshore piping relies on accurately estimating its remnant fatigue life (RFL). Several modeling approaches, such as knowledge-based, model-based, data-driven, fusion techniques etc., have been used to build RFL models in the past. The aim of this paper is to review these approaches and thereby recommend the most favorable approach for building...
Switches and crossings (S&Cs) connect the rail network, guiding trains from one track to another and supporting path crossing. They are critical systems given the frequency of their functional failure and the consequences on the operation, cost and safety of railway transportation. Reliability studies are required to support the transport objective of providing dependable, sustainable and cost...
The prediction of reliability for rubber O-rings used in the rockets is of great significance for the life assessment of the rockets. In this paper, rubber O-rings were aged under accelerated conditions at temperatures ranging from 60°C to 80°C. And a new model based on Wiener process with a time scale transformation was presented to describe the degradation of CS (compression set) which is the characteristic...
This paper focuses on the use of inventory models to control the material flow and purchased inventory items in manufacturing companies. The objectives of this paper are to assess the effects of demand uncertainty on inventory management and to evaluate the difference on uncertain demand subject to demand controls as determined and the models used. Three inventory management models are studied; the...
Inelastic recovery behavior of seamless tubes has been investigated by uniaxial tensile tests. Unloading stress-strain curves for different plastic strain reveals that the percentage of inelastic recovery to the total recovery increases with plastic deformation. The results of this study concludes that with increase in plastic strain, Young's modulus reduces drastically first then reduces somewhat...
Globally distributed Information and Communication Technology (ICT)projects, typically engage multistakeholders coming from diverse multicultural backgrounds, with varied interests and collaborating across remote geographical locations using different technologies. This is viewed as a significant challenge and of strategic importance in the face of stakeholder adversities. This paper builds on scientific...
On account of great significance of financial distress prediction for corporations, it is essential to construct an effective prediction model for managers and investors. Traditional financial distress prediction methods design static models using samples within a period of time, but the static models are insensitive to changes, such as concept drift in financial distress. This paper proposed a dynamic...
Building Information Modeling (BIM) is a set of interacting policies, processes and technologies generating an approach to manage design and project data in digital format throughout the project life-cycle. Although BIM is applied traditionally to the civil industry, the implementation of such a tool seems to be beneficial also for the industrial plants sector. Starting from the assessment of the...
This follow-up study provides a conceptual refinement on the possible linkage between ‘knowledge management maturity’ (KMM) and ‘organizational performance’ within the setting of Indonesia construction firms. A moderating variable of ‘size of organization’ is introduced into the analysis. An empirical study was carried out by means of a cross-sectional survey. Out of 486 questionnaires distributed,...
The online reservation system (ORS) is widely used in the hospitality industries. This paper studies the hotel's optimal pricing policies for two types of contracts: booking without prepayment and booking with prepayment. The hotel adopts these two contracts to segment heterogenous customers through the ORS. We get the hotel's three possible pricing strategies and the corresponding payoffs. It is...
A transformative research paradigm is rooted in knowledge mobilization processes involving close collaboration between researchers and the community. A formalized approach to managing multi-stakeholder participation and community engagement in a science and technology research environment is presented. Design science research methodology is applied with a systems thinking approach to implement an...
Innovation and product development activities in firms in almost all countries rely on the product development teams comprised of across functions. The members of product development team are those coming from various backgrounds, across departments and across areas of science. In many product development projects, team members do not always collaborate as expected due to differences in views and...
The Rural Appliance Rebate Program (RAR) starting at the end of 2010 was part of the efforts of Chinese government to boost up domestic consumption during global economic downturn. While the RAR program's positive effects on macro economics have been well documented, the impacts of such a governmental subsidy program on the companies and the industry are unknown. This paper investigates whether the...
Increasing of population leads to escalation of demand needs which results in busier logistics activitities. Collaborative strategy has become an alternative to manage these activities, depending on the conditions in a certain location. This paper applied collaborative distribution model to Yogyakarta city, in order to see whether the collaboration is beneficial. The performance of collaborative distribution...
