This paper aims to investigate the performance of four different textile materials used as an outer shell of the bulletproof vest.

In this paper, four different textile materials were used, polyurethane treatment was applied as a surface coating for the woven samples. Mechanical properties were conducted for all samples; scanning electron microscope and X-ray energy disperse spectroscopy were executed to show the surface morphology of samples and the chemical composition of the coating material.

One-way ANOVA was used to statistically analyse the results, which proved that all variables were highly significantly affected by using different textile materials, despite the stiffness variable being not significantly affected by textile materials. An overall evaluation was done using radar chart, demonstrated that Cordura material accomplished the best functional performance, using two types of calibres 7.62 × 54 mild steel core and 7.62 × 54 armour piercing incendiary; the common mechanism was localized burn because of the incendiary effect of the projectile in addition to tearing mechanism starting from inside because of penetration effect of the steel core.

This work was addressed to analyse the impact of using four different materials on its performance as the outer shell of bulletproof vest to achieve the desired degree of protection.

Modern IT‐based loans and delivery automation systems combined with video surveillance and monitoring cameras have enabled new service opportunities and models in public libraries. In Denmark, staffless public libraries have appeared recently in many local communities. This article aims to report on the Danish experiences with open libraries in terms of local community characteristics, their use – visits and loans, characteristics of the users in terms of sex and age and, finally, an analysis of critical success factors revealed in association with open libraries.

The data upon which this article is based were collected during the autumn of 2011 by the Danish Center for Library and Media through an electronic questionnaire to all 97 of Denmark's municipalities.

The origins of the concept of open libraries were shaped by the opportunities made by a combination of the technological development of automated loans and delivery systems and electronic surveillance techniques. The open library concept has been described as a success in terms of growth rates of visits and increasing number of loans.

The article shows that the concept has been quite successful in terms of use and local support and that it has strengthened the position of the local public libraries in the local communities.

Passive conducting elements are the important parts of textronic systems. This paper aims to study a possibility of creating well-conducting and durable elements in textile materials by combining two technologies – physical vapour deposition (PVD) and laser patterning.

Thin conducting metallic layers on common fabrics do not provide satisfactory resistance to bending and stretching; therefore, selected textile composite materials have been proposed as a substrate. The conducting elements were produced in two stage process – deposition of thin metallic layer on textile composite and creating conducting elements by laser patterning. Laser ablation process was optimized using modelling in Comsol Multiphysics package. Properties of conducting structures were investigated experimentally and by modelling.

This paper confirms the correctness of the choice of the textile composite as a substrate for conducting elements. The results have shown that combining PVD deposition of thin metallic layer and controlled laser ablation allow creating passive elements such as resistors, inductive coils and heaters. Computer simulations conducted in the Comsol Multihysics environment enabled to determine the temperature distribution around the heaters and to describe the dynamics of its changes. The obtained results allow to shorten time of the optimization process of structures with different geometry and assumed temperature distribution.

The novelty of this research can be summarized as following: choosing of textile composites as substrates for conductive elements instead of textiles used so far in textronics; creating conductive structures on textile composites using combined technologies, PVD and laser patterning, for the first time; modelling of laser ablation process of thin metallic layer; and optimization of properties of conducting elements by computer modelling.

Examines the product life cycle (PLC) concept as presented in much of the marketing literature, and the implications of PLC‐based strategic action for marketing practitioners. A range of problems is identified with the PLC, and an evolutionary perspective for product management decisions is considered. Concludes that an evolutionary perspective is more appropriate than PLC‐based approaches, and proposes an evolutionary model known as “Lamarckism”, which is better able to account for the realities of product evolution than the Darwinian model.

The purpose of this paper is to present supply chain metrics and to propose a fuzzy-based performance evaluation method for lean supply chain.

To understand the overall performance of cost competitive supply chain the paper investigates the alignment of market strategy and position of the supply chain. Since lean is applicable in many supply chains, the authors propose a set of metrics to evaluate supply chain performance. Moreover, the paper uses a fuzzy model to evaluate the performance of cost competitive supply chains. Fuzzy is an appropriate model method when uncertainty is present. It also allows modelling of a significant number of performance metrics across multiple supply chain elements and processes. Competitive strategy can be achieved by using a different weight calculation for different supply chain situations.

Research provides optimal metrics for lean supply chains. The proposed method can measure the performance of lean supply chains using a fuzzy approach and competitive strategies.

The metrics which have been selected to measure the performance of lean supply chains is particularly applicable for high volume, low-price products.

By identifying optimal performance metrics and applying performance evaluation methods, managers can predict the overall supply chain performance under lean strategy. By identifying performance for each metric they can also categorize the existing performance and optimise them accordingly.

This study provides a performance evaluation method for supply chain managers to assess the effects of lean tools and competitive strategies.

The purpose of this paper is to present the quantification of the thermal conductivities and thermal resistances of 12 insulating fabrics extracted from commercial clothing products under static, simulated sweating, and simulated wind chill conditions.

Triplicate coded (blind test) samples of each fabric were tested in a modified ASTM 1518‐85 test apparatus enclosed in a cold box capable of temperatures as low as −85°C to determine thermal conductivity and thermal resistance. Sweat and wind chill were also simulated and evaluated.

One fabric, Vaetrex0, was clearly found to be superior under all conditions to the other 11 fabrics tested. The performance of many of the other fabrics varied when exposed to simulated sweat.

An objective evaluation of fabrics that can assist manufacturers in fabric selection for cold weather clothing manufacture.

The paper provides an extension of the ASTM 1518‐85 method to cold conditions and a unique blind comparison test of commercial clothing fabrics under these extreme conditions.

Ethical decision making, business ethics.

This case is applicable to MBA, EDP and EMBA courses.

TOREAD, a professional provider of outdoor equipment in China, started in business by producing and selling tents. To meet market demand, TOREAD expanded its product line which ranges from outdoor durable tent products to “pan-outdoor” products including footwear and clothing. During the critical expansion phase, TOREAD was challenged by a quality problem in a batch of outsourced sandals that had been manufactured by a contracted supplier. By researching different options and going through an ethical decision making process, TOREAD made the choice of destroying all “problem sandals”. Since then, TOREAD has focused development on product quality improvement and product innovation to establish a sustainable brand image and generate social benefits. TOREAD's decision making in the critical development phase helped it to become the leader in the outdoor product industry in China.

This case may be used for courses such as business ethics and strategy. By learning this case, students can understand the process of making ethical decisions when facing moral dilemmas among corporate decision makers, employees and relevant interested parties, and learn how to make strategic decisions to balance company profit growth and social benefits in critical development phases.
