Stakeholders of construction projects exhibit different perceptions regarding the visibility of materials in the supply chain, which affects the timely delivery and installation of materials. This study aims to quantitatively investigate the differences in viewpoints of owners, contractors, designers and suppliers about the visibility of materials at supply chain locations and different material types during the construction of industrial projects.

Survey data about visibility at nine typical supply chain locations and three common material types were collected from owner, contractor, designer and supplier groups and analyzed using frequency statistics, relative importance index and tests for equality of odds.

Offsite Tier-2 supplier, ports and kitting site shows the lowest visibility level for the owner, contractor, supplier and designer groups. Also, the supplier group tends to have adequate to extreme visibility at the Tier-2 supplier, kitting site and during transportation compared to owner, contractor and designer groups. An example finding concerning the visibility of material types is that owners and contractors perceive prefabricated material requires higher visibility than all other material types.

The findings are limited to construction projects in the industrial sector. Further, the survey participants were based in North America at the time of participation.

The study’s findings indicate how visibility is spread across supply chain locations and for material types for the owners, contractors, suppliers and designers of industrial projects. As such, academia and industry’s research and investment efforts can be more focused on locations and material types that need improvement.

Industrial projects play an essential part in improving society’s daily lives, and this study’s findings contribute to improving the efficiency of the supply chain during construction of industrial projects.

Although previous studies mentioned the need and importance of visibility improvement, none have sought to understand the perception of leading supply chain stakeholders about visibility at supply chain locations and of material types. This study’s findings provide specific insights and directions for advancing in these areas with regard to supply chain visibility.

In the new retail era, the supply chain synergy produced by quality integration has become the new direction of service supply chain research. The purpose of this paper is to study how to promote the sustainable development of the retail service supply chain (RSSC) by comparing and analyzing the optimal quality behavior, optimal returns, and the combination of conditions and strategies of the participating members of the RSSC.

From the perspective of quality function development and service quality concern, this paper considers RSSC as a two-level supply chain structure composed of functional service provider and retail service integrator. In this paper, a dynamic optimization model of quality input-cooperation-coordination of RSSC is proposed under two quality cooperation modes of decentralization and integration. This paper adopts the differential game method to compare and analyze the optimal quality behavior, optimal income, forming conditions and strategic combination of the participating members of the RSSC in different situations.

(1) Compared with quality dispersion, quality integration has more significant Pareto improvement effect on quality behavior and optimal revenue of RSSC. (2) In the case of quality integration, the optimal revenue obtained by the service sharing model is generally better than that obtained by the retail alliance collaboration model. (3) Benefit distribution ratio and quality cost allocation determine the optimal quality behavior of participating members of the RSSC, and also become the key factors for participating members to choose the collaborative mode in the case of quality integration.

Based on the quality function development of RSSC, this paper introduces the concept of steady service quality, and discusses the relationship between the quality cooperation stability and the mode selection of RSSC. This provides a theoretical basis for how to build a RSSC with efficient operation and stable quality.

OF old the public library was wont to take its reputation from the character of the newsroom. That room, as everyone knows, attracts every element in the community and it may be it attracts especially the poorer elements;—even at times undesirable ones. These people in some towns, but perhaps not so often now‐a‐days, have been unwashen and often not very attractive in appearance. It was natural, things being as they are, that the room should give a certain tone to the institution, and indeed on occasion cause it to be avoided by those who thought themselves to be superior. The whole level of living has altered, and we think has been raised, since the War. There is poverty and depression in parts of the country, it is true; but there are relief measures now which did not exist before the War. Only those who remember the grinding poverty of the unemployed in the days, especially the winter days, before the War can realise what poverty really means at its worst. This democratic levelling up applies, of course, to the public library as much as to any institution. At present it may be said that the part of the library which is most apparent to the public and by which it is usually judged, is the lending or home‐reading department. It therefore needs no apology if from time to time we give special attention to this department. Even in the great cities, which have always concentrated their chief attention upon their reference library, to‐day there is an attempt to supply a lending library service of adequate character. We recall, for example, that the Leeds Public Library of old was first and foremost a reference library, with a lending library attached; to‐day the lending library is one of the busiest in the kingdom. A similar judgment can be passed upon Sheffield, where quite deliberately the city librarian would restrict the reference library to works that are of real reference character, and would develop more fully the lending library. In Manchester, too, the new “Reference Library”—properly the new Central Library—has a lending library which issues about 1,500 volumes daily. There must be all over the country many libraries issuing up to a thousand volumes each a day from their central lending departments. This being the case the department comes in for very careful scrutiny.

The purpose of this paper is to present relationship between operation and management practices analyzing the results achieved by both public organizations prone to deploy Lean Six Sigma (LSS) and public organizations that have already implemented the method. The goal is to support the start of method deployment by public managers and the creation of more efficient and effective processes in public organizations.

An analysis of synergies between findings in the multiple case study carried out in Brazilian public organizations from health and education sectors and successful implementations found in the LSS literature is made.

The fact that this research comprised organizations from different segments allowed good practices and difficulties to be identified in a unique way, adding more value to the research carried out and increasing the potential of support to the public manager. In addition, it was possible to map the most mentioned benefits of LSS deployment in both health and education sectors and link them to systematized LSS practices.

The presenting research should initiate a scientific discussion on public sector areas more prone to LSS and guide researchers in the development of case studies aimed at the application of this method in public organizations in general.

This paper can assist public managers to become aware of the potential of the organization they manage in the adoption of LSS principles and practices enabling a better quality of services provided to citizens.

The finding that public health organizations are more likely to implement LSS principles and practices when compared to public organizations from other segments can guide more in-depth studies that justify why some organizations would be better able to implement the LSS method and others would face more difficulties in a hypothetical deployment.

THE effective little conference of the London and Home Counties Branch of the Library Association at Brighton gave clear proof of the value of and desire for such gatherings. This experience, we are confident, will be understood by our Council and a national conference should be possible in 1946. At Brighton, amongst many good things, from the public lecture by Charles Morgan to the excellent symposium by the Service members, there was the important statement by Mr. Goldsack, Chairman of the National Book League and a well‐known publisher, on the state of British stocks of books. A census made by publishers and booksellers had revealed that some 50,000 basic books, which are required continuously by libraries, schools and the general reading world, are out‐of‐print. It may be recalled that forty years ago James Duff Brown asserted “of real, living works of literary and human interest, there are perhaps not more than 20,000 in the English language,” and if more than twice that number of books are unavailable the condition would seem to be parlous. Of course the quotation we have made is not acceptable today nor is the statement unqualified in the Berwick Sayers' editions of Brown's Manual, but Mr. Goldsack's figures give us furiously to think. We are bound to keep in every town and county a representative collection of books of every age and we do know that there is the insistent demand for current books; for some readers, indeed, this means current fiction; lacking that we are labelled as “useless” by the most vocal part of the community of readers.

Some libraries and information services are quite definitely user‐centred; some think they are but are not always; some seem to be designed for librarians rather than users. The purpose of this monograph is to encourage the development of libraries to meet the perceived needs of users — I hope it will be found useful by librarians and information workers as well as by students.

The purpose of this paper is to develop a simulation-based value function (VF) that combines multiple key performance indicators (KPIs) into a unified Sigma rating (SR) for system-level performance assessment and improvement.

Simulation is used as a platform for assessing the multiple KPIs at the system level. A simple additive VF is formed to combine the KPIs into a unified SR using the analytical hierarchy process and the entropy method. Value mapping is utilized to resolve the conflict among KPIs and generate a unified value. These methods are integrated into the standard Six Sigma define-measure-analyze-improve-control (DMAIC) process.

Simulation results provided the Six Sigma DMAIC process with system-level performance measurement and analysis based on multiple KPIs. The developed VF successfully generated unified SRs that were used to assess various performance improvement plans.

The accuracy and credibility of the results obtained from using the proposed VF are highly dependent on the availability of pertinent data and the accuracy of the developed simulation model.

The proposed approach provides Six Sigma practitioners and performance mangers with a mechanism to assess and improve the performance of production and service system based on multiple KPIs when conducting Six Sigma studies.

This paper contributes to the previous research by handling multiple KPIs in Six Sigma studies conducted at the system level using simulation and VF. The research also provides guidelines for using the different methods of weights assessment to form the VF within the DMAIC process.
