Abstract
Purpose
In the case of mass customization, product variety leads to exponentially increased variation in the production system. Providing flexible manufacturing solution for customized product rapidly is the key measure to achieve the goal of cost and delivery time. The purpose of this paper is to address these issues.
Design/methodology/approach
Following introduction, the paper describes flexible manufacturing and numerical control (NC) machining techniques in mass customization. The kernel idea is that NC program for mass customization product should be generated from parametric manufacturing information template, so as to achieve NC program variant design in accord with product variant design. The elements of NC programming system discussed in this paper address the definition of machining feature, the development of NC subprogram, template construct, and the architecture of NC programming system for mass customization product.
Findings
Machining feature, NC subprogram, and template are made to help manufacturing system to deal with the increased variation requirements resulting from product variety. The effects can be verified by the case study.
Originality/value
This paper provides a practical NC programming system for mass customization product and makes detailed technical solution to manufacturing system developer and its applications.

Abstract
Tourism planning is an important issue for destination management organizations to satisfy both local community and tourists. This chapter attempts to explain the process and outcomes of a strategic and participative tourism planning project through a case study in Patagonia, Argentina. The general framework of the study, principles of cooperation throughout the project, the geographical information, stages of planning and implementation strategies will be discussed.

Abstract
For decades, the Department of Defense (DoD) has employed numerous reporting and monitoring tools for characterizing the acquisition cost estimates of its programs. These tools have led to dozens of studies thoroughly documenting the magnitude and extent of DoD acquisition cost growth. However, little attention has been paid to the behavior of the other main cost component of a system's life cycle cost: Operating and Support (O&S) costs. Consequently, the DoD has little knowledge regarding the accuracy of O&S cost estimates or how that accuracy changes over time. In a previous paper, the authors described an analytical methodology for remedying this deficiency via a study to characterize the historical accuracy of O&S cost estimates. The results are presented here, and indicate there tend to be large errors in DoD O&S cost estimates, and that the accuracy of the estimates improves little over time

Abstract
Purpose
This paper aims to analyze strategies that promote sustainability in higher education institutions (HEIs), focusing on the case study of a federal institute of higher education in Brazil.
Design/methodology/approach
The research was based on a scientific literature review on sustainability in HEIs, to identify the recurrent actions for sustainability in these institutions; and a case study of a federal institute of higher education in Brazil, to illustrate how these actions are being implemented by HEIs.
Findings
Concerns about sustainability, prompted by the Brazilian federal legislature, led federal HEI to change its internal processes, infrastructure and organizational culture toward sustainability.
Practical implications
The findings presented in this study, more specifically the sustainability plan of the Federal Institute for Education, Science and Technology of Santa Catarina, aligned with the recommendations proposed, can be used and replicated in other HEIs.
Originality/value
Scientific literature about organizational changes led by sustainability concerns, in HEIs specifically, still needs more attention in the academia. By addressing the case of a Brazilian public institution of higher education, this paper contributes to the literature on sustainability in higher education by reporting the process of implementation of a sustainability plan.

Abstract
There is a widely available object oriented (OO) programming language that is usually overlooked in the OO analysis, OO design, OO programming literature. It was designed with most of the features of languages like C++, Eiffel, and Smalltalk. It has extensive and efficient numerical abilities including concise array and matrix handling, like Matlab®. In addition, it is readily extended to massively parallel machines and is backed by an international ISO and ANSI standard. The language is Fortran 90 (and Fortran 95). When the explosion of books and articles on OOP began appearing in the early 1990s many of them correctly disparaged Fortran 77 (F77) for its lack of object oriented abilities and data structures. However, then and now many authors fail to realize that the then new Fortran 90 (F90) standard established a well‐planned object oriented programming language while maintaining a full backward compatibility with the old F77 standard. F90 offers strong typing, encapsulation, inheritance, multiple inheritance, polymorphism, and other features important to object oriented programming. This paper will illustrate several of these features that are important to engineering computation using OOP.

Abstract
Purpose
The purpose of this paper is to analyze and evaluate the present liquidity management in the Indonesian Islamic banking industry. It also proposes an integrated and comprehensive program of liquidity risk management which captures and assimilates the whole aspects of the issue and brings the industry into a better way of managing liquidity risk based on sharia principles.
Design/methodology/approach
The paper first examines the organizational structure of Islamic banks and Islamic windows in managing liquidity. Second, it investigates the characteristics of the depositors, their investment behaviors and expectations followed by the banks efforts and policies to manage the liquidity. Then, it identifies the potential liquidity problems and Islamic liquid instruments. Finally, it proposes an integrated and comprehensive program for managing liquidity.
Findings
The paper suggests institutional deepening; restructuring the liquidity management on the liability and asset sides; and revitalizing the usage of the Islamic liquid instruments, in the integrated program.
Originality/value
This is believed to be the first paper to propose a liquidity management improvement program in the Indonesian Islamic banking industry.

Abstract
Purpose
The purpose of this paper is to describe an approach towards code validation of RISC microcontrollers, which helps to automate software debugging. A static machine code analysis which checks the appropriateness of instructions in a sequence to identify any logical mistakes and also to identify redundant codes appearing in a program for the target processor is presented.
Design/methodology/approach
Validation is done with the help of rules of inferences formulated for the target processor. The rules govern the occurrence of illegitimate/out of place instructions and code sequences for executing the computational and integrated peripheral functions. The stipulated rules are encoded in propositional logic formulae and their compliance is tested in all possible execution paths of the application programs. An incorrect sequence of machine code pattern is identified using slicing techniques on the control flow graph generated from machine code.
Findings
The results explain that the technique is independent of compiler/assembler and contributes to early detection of software bugs that are otherwise hard to detect. Program states are identified mainly with machine code pattern, which drastically reduces the state space creation contributing to an improved state‐of‐the‐art model checking.
Research limitations/implications
Though the technique described is general, the implementation is highly architecture oriented, and hence the feasibility study is conducted only on PIC16F87X microcontrollers.
Practical implications
This validation tool can be integrated to the system development environment resulting in improved software quality and reduced debugging time.
Originality/value
It is a novel and original approach at machine code level applicable to a wide range of processors once appropriate rules are available.

Abstract
The paper describes the use of STATUS by TRRL's Technical Information and Library Services to mechanize the library's document ordering, cataloguing, loans control and to integrate these functions with a cooperatively‐acquired international database of abstracts — all in a single document record. Modifications made to standard STATUS to meet TRRL's needs are described and the good and bad features of STATUS as found in practice are outlined.
