MERGING OPTIMALITY CONDITIONS WITH GENETIC ALGORITHM OPERATORS TO SOLVE SINGLE MACHINE TOTAL WEIGHTED TARDINESS PROBLEM

1.Introduction Production sequencing and scheduling is one of the most important activities in production planning and control.Sequencing is defined as the order in which the jobs are processed through the machines.The allocation of machines over time to process a collection of jobs is defined as Scheduling.Several methods have been developed to solve the scheduling problem which can be classified as follows:1)efficient optimal methods,2)implicit and explicit,or complete enumerative methods,a…     

MODELING JUMPS IN RETURNS OF FINANCIAL ASSETS AS M4 PROCESSES： MEASURED EXCHANGE RATE EXPOSURE OF ASIAN EQUITY PORTFOLIO

1. Introduction An early analysis of exchange rate changes and share prices found that the general stock market index tended to move up (down) immediately after a devaluation (revaluation) of the local currency (Giddy 1974). It is surprising that previous researches (Jorion 1990; Amihud 1993; Bodnar and Gentry 1993) find that no contemporaneous relationship between exchange rate changes and excess equity market returns of largest U.S. exporting firms. Recently, it has argued that there is a…     

MODELING COMMERCIAL PROCESSES AND CUSTOMER BEHAVIORS TO ESTIMATE THE DIFFUSION RATE OF NEW PRODUCTS

1. Introduction In his famous seminal book (Rogers 1962), Rogers introduced and popularized a generic framework for analyzing and describing how the mechanism of diffusion of innovations works inside a given population. In this general approach, “innovation” can of course be understood in a large way: it may indeed referto various contexts such as the learning of a new practice, the use of a new tool, the launch of a new product, etc. The strength of Rogers' point of view comes from the fac…     

MAN-MACHINE COLLABORATED KNOWLEDGE CREATION IN HWMSE

1 Introduction Science of complexity and complex systems is a relatively new area In wide fields from chemistry, biology, environment, geo-science, climatology to economics and sociology, complexity has been studied from diverse views and understandings Systems science, which could be traced back to Ludwig von Bertalanffy’foundational work on general system theory, plays an active role in complexity studies From system perspectives, relevant concepts often include interaction, feedback, evol…     

Operationalising “Double-Loop” Learning in Service Organisations: A Systems Approach for Creating Knowledge

Learning organisation literature has widely discussed the connections between “double-loop” learning and its significance to organisational performance, but paying little attention to tools and systems that can operationalise “double-loop” learning in organisations. This paper investigates the impact of applying a systems approach for service operations design, expressed as the Vanguard Method (Seddon, Freedom from command and control: a better way to make the work work, 2003), in order to activate “double-loop” learning in service organisations. Two case studies were conducted in the banking mortgage operations and adults’ social care services in the UK, using the dimensions of the learning organisation questionnaire (DLOQ), semi-structured interviews, observations, and documents. The findings of the cross-case analysis support the link of applying the Vanguard Method with operationalising “double-loop” learning through three main factors, namely systematic-operations improvement, organisational capacity development, and outside-in mode of work; that are all embedded into the seven dimensions of the DLOQ. The value of this paper is the introduction of a service operations design tool that can activate “double-loop” learning performance in the fast changing knowledge era. It also provides an impetus for service organisations to creatively influence employees’ competencies to effectively improve internal systems.     

Systemic Development of Leadership: Action Research in an Indian Manufacturing Organization

This insider action research study differentiates between developing leaders and leadership, evolves a systemic leadership model, and intervenes on the human, social and processes dimensions for developing leadership. This is a real-time study and responds to the organizational reality of fast pace of change and its systemic nature. Consequently, the research too is fast to guide actions and influence positive changes in the organization. As the action research addresses a systemic reality, research and contributions are in multiple aspects, with new techniques having huge implications for theory building as well as improving practice. The study provides a structural solution to perceived lack of commitment in senior colleagues—a syndrome I acronym as HILE (High Intentions and Lukewarm Execution)–by re-designing organizational processes and making time available for its effective utilization in developing leadership. A new technique of triggering major changes in organizations termed “concept sublimation” distils concept from the statements of major stakeholder and sublimates it from lower to higher unit of analysis and to higher levels of positivity. Statistical simplification of a competency framework by applying concepts from Euclidian geometry and making it effective is yet a unique contribution of this action research study. The study adapts the competing values framework in developing a method of assessing cultural congruence of a candidate with the culture of the organization. The uniqueness of the study lies in bridging the gap in the literature by actually and systemically developing leadership in an organization and providing pragmatic insights on developing leadership while also creating knowledge for theory building.     

Building Organizational Identity: an Insider Action Research from a Founder’s Viewpoint

This paper features the implementation of an extensive insider action research, exhaustively following the framework of Coghlan and Brannick (2010, 2014). It consisted of two action research projects - the thesis action research and the core action research - which were done in a parallel manner, both following the iterative cycles of constructing, planning, taking, and evaluating action. The thesis action research was aimed at developing a theory on building organizational identity from the viewpoint of an organizational founder. On the other hand, the core action research was focused on promoting the specific identity of the Institute for Integrality, Inc. Quality and rigor were observed in the implementation of the action research cycles. In the fieldwork, there were three main cycles undertaken – understanding organizational identity, fine-tuning the practice of this identity, and designing the integration of this identity in organizational culture. Thereafter, significant learnings were derived from meta-learning in the form of content, process, and premise reflections. Finally, through the critical reflection of the project in the light of the experience and theory, A-Founder’s Integrative Theory of Organizational Identity Building was derived.     

Backstepping approach to the adaptive regulator design for a one-dimensional wave equation with general input harmonic disturbance

This paper considers the parameter estimation and stabilization of an unstable one-dimensional wave equation with matched general harmonic disturbance at the controlled end. The backstepping method for infinite-dimensional system is adopted in the design of the adaptive regulator. It is shown that the resulting closed-loop system is asymptotically stable. Meanwhile, the estimated parameter is shown to be convergent to the unknown parameter as time goes to infinity.     

Bell state preparation based on switching between quantum system models

For the preparation of any target Bell state under continuous quantum measurement, this paper proposes a method which achieves the control objective by switching between two different models or by switching between two control channels under one model. Proper control Hamiltonians are selected for the two system models, a switching strategy between the two models is designed, and the stability of the whole switching system is proved in theory. For a given target Bell state, the effectiveness of the proposed switching control strategy between different models is illustrated through simulation experiments.
