Presented in this paper was to evaluate and improve the usability of a web-based logistics information system. The system was developed for the domestic company to track and monitor its own transportation vehicles and for the customers to check the current location of their packages by using Global Positioning System (GPS) and Short Massage Service (SMS). Since the initial system was developed under a tight schedule set by the company, the system designers and programmers did not focus on the usability of the system but on the functionality. Consequently, some usability problems of the system were discovered during the heuristic usability evaluation. This study was required to solve these usability issues. Usability problems of the initial system were identified and analyzed, and the user's requirements for the system were re-evaluated to meet the company's expectation. Several alternative designs were developed by fitted guidelines and then a updated system was developed. The updated system had an empirical usability test to find how much the initial system was improved from the heuristic evaluation. Two kinds of data were gathered during the tests: objective (completion time and number of errors) and subjects' preference. Data showed the updated system is better than the initial system in terms of usability. Presented in this paper includes introduction of the Usability evaluation, usability engineering process applied in this research, alternative design of GUI, usability test and results.

Purpose - This study aims to verify the direct causal relationship between cost competitiveness and global network competitiveness, which are the tangible service quality factors determined by the shipping company, which in turn affect the shipper's customer satisfaction. Additionally, we empirically investigate the intangible, related service qualities determined by shipping companies, such as operational competitiveness and customer relationship quality, and how these then positively affect customer satisfaction through the formation of trust. Therefore, we examine the mediating effect of trust formation among different contractors for shipping services. Design/methodology - In order to examine the shipping company's tangible and intangible service-qualities perceived by the shipper on customer satisfaction and the process of trust formation between contractors, we collected valid data from 114 respondents out of 200 distributed questionnaires. The respondents consisted of domestic freight forwarders who engage with domestic and international shipping and logistics agencies. Descriptive statistics, confirmatory factor analysis, reliability, convergent and discriminant validities, common method bias, and PLS-SEM (partial least square-structural equation model) were analyzed using the program STATA 16. Findings - The findings of this study are as follows. First, our results showed that all hypotheses assumed in this study had statistically significant supporting evidence. Second, it was found that the mediating effect of trust was significant in affecting the quality of intangible service- qualities for customer satisfaction. Third, through supplementary analysis, we found that the global network competitiveness of domestic shipping companies will increase in importance in the future. In conclusion, the theoretical and practical implications of these findings are presented. Originality/value - This study reaffirmed the traditional causal relationship between customer satisfaction and tangible service quality. Additionally, we also contribute to the literature on the understanding of the causal relationship between trust formation and customer satisfaction through intangible interactions from a long-term perspective.

Purpose - This study aims to (a) analyze local citizens' perception of a local company, the Gwangyang Steel and Iron Company (GSIC); (b) compare the perception toward the local company with that of national citizens' perceptions towards many other unspecified companies, which were surveyed biannually by The Korea Chamber of Commerce and Industry (KCCI); and (c) analyze how such companies evaluate perceptions towards them, in relation to citizens' socioeconomic position, such as their education status. Research design, data, methodology - The data were collected using a questionnaire, which was given to a sample of local citizens in cities. To test the hypotheses, factor analyses, a t-test, and an ANOVA were conducted. The total number of respondents was 1798. The data gathered from the respondents of the sample were analyzed using SPSS Win 19.0 software. Perception towards the company was evaluated on the corporate favorite index (CFI). The CFI index shows how positive citizens feel towards a company. It is calculated using five leading factors, consisting of the following: contribution to the economy, productivity, international competitiveness, social contribution, and ethical management. The higher the level of positive feelings exhibited, the closer the index will come to 100. Results - As a result of the analysis, the CFI index towards the GSIC stood at 67.3. The CFI index towards the company is 16.5 points higher than that of the index towards the many other unspecified companies, which were surveyed by the bi-annual KCCI study in the first half of 2011. The other five indexes stood as follows: contribution to the economy, productivity, social contribution, and ethical management was 69.2, 71.2, 64.6, and 58.6, respectively. These indexes are 18.3, 4.6, 27.6, and 35.6, respectively, higher than those found by the KCCI study. However, international competitiveness is 73.0 (9.8 points lower than that of the KCCI study). This survey thus shows that the CFI of the local citizens towards the global company GSIC is very high when compared with the CFI index towards the many other unspecified companies that was determined by the KCCI survey. Conclusions - This survey shows that local citizens have high expectations of economic activity, increasing working opportunities, and regional cooperation projects from the local company, GSIC. In addition, the CFI index towards GSIC evaluates results depending on the respondent's relationship with the company, and their educational status. Respondents, whose family or relatives were working as employees of GSIC, have relatively positive perceptions of GSIC, and respondents with a relatively higher educational status also share positive perceptions. Local citizens expect the profit-making of the company to operate in accordance with management activities, and at the same time, they expect that the wealth generated by the company will return to wider society.

The change of the development of transport and logistics systems occurs with the active change of technology and the advent of the era of Industry 4.0. It requires modernization of approaches to the development of transport and logistics systems at the macro and micro levels. The present study aims to identify perspective directions of development and evolution, find out the existing obstacles in the integration of technological solutions of transport and logistics systems at the macro and micro levels. This study is based on a quantitative and qualitative methodology for assessing the level of integration of technologies into transport and logistics systems to study the prospects for their development at the micro level. Macroeconomic indicators of transport and logistics in the context of different regions of the world were used to quantify the development prospects. For a qualitative assessment of the development of the transport and logistics system, the case study method was used. The object of the study was selected logistics company Sensco Logistics Inc., Austin TX. At the macro level, countries with more innovative logistics sectors have stronger mechanisms for coordinating private sector activities. Simplification of administrative procedures of control and regulation by the public sector in order to facilitate trade between countries is a promising direction for the development of transport and logistics systems. Such reforms are more effective in developing a "rigid" transport infrastructure. The integration of Industry 4.0 technology solutions into the international logistics sector is defined by political and legal barriers, especially in developing countries. In low-income countries, hard and soft infrastructure reforms are hindering the development of logistics companies that provide transport services. This determines the national level of development of transport and logistics systems, and in general the global level of development of transport and logistics. In developed countries, the legal barriers to the development of new technological logistics are environmental requirements for the integration of technologies into the transport system. These trends are slowing down the development of International Logistics, which, compared to other industries, is slower to integrate Industry 4.0 technologies. This study combines macroeconomic factors that determine the prospects for the development of transport and logistics systems at the micro level.

This research focuses on the process improvement of port logistics by using Lean methodology. On the one hand, we firstly analyze the current situation and weakness of the processes in port logistics, and then re-design the current processes by the principles of Lean discipline. Based on the appropriately changed processes, the improvement scheme of port logistics will be figured out. On the other hand, we construct the port logistics system by implementing the improved processes. The port logistics' processes accomplished in steel company will be further assorted and identified. The relationship of wharves process, operational process, shipping process, construction process, quality process, and purchasing process are also defined. Every process has been improved by Lean Tools in order to analyze the value added or non-value added processes, to improve the service level, and to reduce the cycle time, inventory, changing time, re-working and waste. Based on above, the appropriate environment that is suitable to Lean process of port logistics will be established and the modeling that can help to implement the improvement scheme will be figured out.
