Abstract
Purpose
The purpose of study is to investigate effectiveness of pattern technique in relation to the use of anthropometric references for drafting women's basic bodice patterns by assessing characteristics of pattern formation, quantification of wearing ease on the transverse plan and actual ease distribution on body forms.
Design/methodology/approach
Three pattern drafting techniques were analyzed, which have different frequency of using direct body measurements for pattern formulation. Ease quantification and wearing ease distribution were evaluated on the two different body forms: a young female body and a heavy woman body. Women's basic bodice patterns were drafted with YUKA CAD and virtually draped on the two body forms with CLO 3D. Rapidform was used to evaluate garment appearance. Areal ease and its distribution were assessed. A deviation map was used for wrinkle analysis.
Findings
Compared to the pattern formation derived from few anthropometric references, patterns using sufficient anthropometric references provided overall better fit for the different body forms. Ease distribution without considering body arcs was found to be a cause of garment fit problems. Patterns with little or no ease caused transverse fine wrinkles and skewed side seams. Pattern techniques those used linear equations caused problems on the bust because the formulation could not reflect bust protrusions in relation to the body torso shape differences.
Originality/value
This study revealed characteristics of pattern formulae and linear equations in relation to anthropometric references and body shapes. The findings may be effective in developing algorithm of the customized pattern formation in the industry.

Abstract
Avı Friedman's new book, DECISION MAKING FOR FLEXIBILITY IN HOUSING has much going for it. The main arguments and objectives are set out here in this manuscript which opens with a short introduction whose first sentence is “narrow houses were a product of necessity”. It goes on to cover facets of his work in this area on construction technologies, and materials arguing also for higher density living. He succinctly makes a case for the narrow frontage town house derived out of the concerns related to environmental and socio-economic issues. Sustainability, among other key factors, recieves full attention making this book and manuscript worthwhile having on your bookshelf and in your University library.(page 6)

Abstract
Dynamic lot sizing is the problem of determining the quantity and timing of ordering items while satisfying the demand over a finite planning horizon. This paper considers the problem with two practical considerations: minimum order size and lost sales. The minimum order size is the minimum amount of items that should be purchased and lost sales involve situations in which sales are lost because items are not on hand or when it becomes more economical to lose the sale rather than making the sale. The objective is to minimize the costs of ordering, item , inventory holding and lost sale over the planning horizon. To solve the problem, we suggest a heuristic algorithm by considering trade-offs between cost factors. Computational experiments on randomly generated test instances show that the algorithm quickly obtains near-optimal solutions.

Abstract
This paper presents a case study on the problem of loading air containers in air express carriers motivated from DHL and Air Hong Kong. The problem is to determine the containers to be loaded and the locations of the loaded containers in an aircraft while maintaining stability of the aircraft. The objective of the problem is to maximize the revenue obtained from delivering containers. We present an integer programming model to represent and optimally solve the problem. Computational experiments done on a number of randomly generated test instances show that the integer program can be a viable tool for generating loading plans in the companies since optimal or near-optimal solutions for the test instances are obtained within a reasonable amount of computation time.

Abstract
In today’s multi-channel distribution environment, it is crucial for the competitiveness of retail stores and companies to improve efficiency of dedicated logistics centers (DLCs) servicing types of retail outlets such as large retail-stores, super supermarkets, and convenient stores. This paper derives efficiency improvement strategies for DLCs through efficiency analyses. To this end, this paper empirically analyzes the efficiency of DLCs by applying DEA (data envelopment analysis) approaches using real data from a Korean distribution company. In detail, this paper analyzes operations, finance, and service efficiencies of DLCs and performs a comparison analysis on the efficiency between DLCs. Finally, this paper discusses the analysis results considering the DLCs’ characteristics and derives managerial and operational implications.

Abstract
We consider the problem of assigning ship assembly blocks to storage locations at a ship yard while allowing one-way movement of the blocks. The objective is to minimize the number of blocks obstructing other blocks’ movements. We show that the integer program in a previous study contains errors in identifying obstructive blocks and therefore, suggest another integer program without the error. Also, we suggest construction heuristics and a tabu search algorithm using properties characterizing optimal solutions of subproblems. Computational experiment results indicate that our heuristics outperform the existing algorithm in terms of solution quality.

Abstract
Purpose
The new age of entrepreneurs recognizes crowdfunding as an innovative and effective means of obtaining funding from backers. However, attracting backers is challenging and related scholarly knowledge lacking. Therefore, this study investigates the diverse factors influencing backer funding intention in reward-based crowdfunding.
Design/methodology/approach
This study conducted an online survey of 401 registered backers from two reward-based crowdfunding platforms in Taiwan. Data were analyzed using covariance-based structural equation modeling.
Findings
Results show that entrepreneur activeness has a negative effect on perceived risk but positively, while entrepreneur activeness and platform interactivity have a positive effect on backer engagement and backer value creation. Although it had no significant impact on backer engagement, project novelty positively influenced backer value creation. Perceived risk had no influence on either backer engagement or backer value creation. Backer engagement positively influenced backer value creation and backer funding intention, with the former having a positive impact on the latter.
Originality/value
This study provides a multi-perceptual lens by proposing an integration of diverse factors such as entrepreneurial- (entrepreneur activeness), project- (project novelty and perceived risk) and platform-related characteristics (platform interactivity) as antecedents to backer funding intention. By integrating a service-dominant logic perspective into the stimulus-organism-response model, this study highlights the essence of value creation by perceiving backers as value co-creators.

Abstract
The strategic location of city logistics facilities may help to establish more efficient urban logistics systems, reduce social and environmental costs of urban freight transport, and improve urban traffic conditions. In addition, it may allow a number of shippers or freight carriers to jointly operate freight vehicles and terminals or information systems while allowing them to have the capability to provide higher levels of services to their customers. This paper considers the problem of selecting a location for a city logistics facility while considering linguistic factors. This paper identifies the important factors in the selection of a location for a city logistics facility by performing a case study which applies the analytic hierarchy process method on data from Chongqing, China. The optimal location in Chongqing is then determined by using the fuzzy synthetic evaluation method. The results of this paper are expected to help municipal governments select appropriate locations for city logistics facilities and quantify the advantages and disadvantages of alternative locations.

Abstract
Purpose
Using consumption value theory, this study aims to examine the impact of tourists’ perceived consumption value dimensions of tea beverages offered by Hong Kong (HK)-style cafés, including taste value, price value, health value and emotional value, on tourists’ memorable experience (ME), satisfaction and revisit intention.
Design/methodology/approach
Using an online survey, this study collected 225 usable data from tourists who had experience in visiting HK-style cafés. Partial least squares–structural equation modelling was used to examine the importance of tourists’ value dimensions, including taste value, price value, health value and emotional value, on tourists’ ME, satisfaction and revisit intention.
Findings
The results revealed that taste value, price value, health value and emotional value are significant predictors of tourists’ ME in HK-style cafés, which in turn drive their satisfaction and revisit intention.
Research limitations/implications
This study focusses on a single context: HK-style cafés. Future research may enhance the generalisability of the findings by replicating the model in other countries with diverse cultures.
Practical implications
Tourism marketers may strengthen tourists’ ME, satisfaction and revisit intention by promoting tea beverages as well as HK-style cafés. Tourism marketers are recommended to communicate taste value, price value, health value and emotional value of HK-style tea beverages, which in turn encourages tourists to learn about the features of tea beverages. Subsequently, it drives tourists’ ME and satisfaction, thereby strengthening their intention to revisit.
Originality/value
This study contributes to the tourism marketing literature by providing an understanding of the role of tea beverage value in driving tourists’ ME, satisfaction and revisit intention. By empirically testing a research model, this study confirms that specific consumption value elements of tea beverages, namely, taste value, price value, health value and emotional value, are critical drivers in driving tourists’ ME, satisfaction and revisit intention.

Abstract
Unlike the building forms, technology, and materials of today, the traditional Korean architecture represents an example of flexible building forms in history. Investigating and studying this type of architecture not only can contribute to the reform of architectural history by understanding how ordinary buildings change over time and how they interact with people but also may suggest the possibility of, and methodology for developing long-lasting and sustainable mass housing in Korea and in Asian cities. The first part of the paper demonstrates the structural, spatial, and functional flexibilities of traditional Korean architecture. The second part investigates the construction system, including the organization of builders and the regulations governing the relationship with the residents. Its systematic construction approach is associated with the specialization of construction and standardization and prefabrication of elements, facilitating the easy replacement and reuse of building materials. The paper is based on a research methodology of integrating historical archives and case studies. The main argument posited here is that knowledge and skill of traditional construction of flexibility suggest conceptual strategies to improve current housing design and construction in order to obtain a sustainable future.
