Abstract

Purpose

The purpose of this paper is to examine how certain limitations of the current approaches to planning and scheduling of aircraft heavy maintenance can be addressed using a single integrated framework supported by unified data structures.

Design/methodology/approach

The “unitary structuring technique”, originally developed within the context of manufacturing planning and control, is further enhanced for aircraft heavy maintenance applications, taking into account the uncertainty associated with condition‐based maintenance. The proposed framework delivers the advanced functionalities required for simultaneous and dynamic forward planning of maintenance operations, as well as finite loading of resources, towards optimising the overall maintenance performance.

Findings

Execution of maintenance operations under uncertainty involves materials changes, rectification and re‐assembly. It is shown that re‐scheduling of materials (spare‐parts), resources and operations can be taken care of by simultaneous and dynamic forward planning of materials and operations with finite loading of resources, using the integrated framework.

Research limitations/implications

As part of adopting the proposed framework in practice, it needs to be guided by an overall methodology appropriate for application‐specific contexts.

Practical implications

The potential direct benefits of adopting the proposed framework include on‐time project completion, reduced inventory levels of spare‐parts and reduced overtime costs.

Originality/value

Existing approaches to aircraft maintenance planning and scheduling are limited in their capacity to deal with contingencies arising out of inspections carried out during the execution phase of large maintenance projects. The proposed integrated approach is, capable of handling uncertainty associated with condition‐based maintenance, due to the added functionalities referred to above.

Abstract

Computer aided process planning (CAPP) is generally acknowledged as a significant activity to achieve computer‐integrated manufacturing (CIM). In coping with the dynamic changes in the modern manufacturing environment, the awareness of developing intelligent CAPP systems has to be raised, in an attempt to generate more successful implementations of intelligent manufacturing systems. In this paper, the architecture of a hybrid intelligent inference model for implementing the intelligent CAPP system is developed. The detailed structure for such a model is also constructed. The establishment of the hybrid intelligent inference model will enable the CAPP system to adapt automatically to the dynamic manufacturing environment, with a view to the ultimate realization of full implementation of intelligent manufacturing systems in enterprises.

Abstract

Purpose

The aim of this paper is to advance applied theoretical knowledge on international business (IB) ideation by designing the managing of such ideation as three recursive, multi-competence-enabled systems.

Methodology/approach

The core principles of Beer’s (1985) Viable System Model are adopted for this system design task. The Viable System Model consists of five interacting sub-systems that can support a viable IB unit.

Findings

The contribution of this design of the three recursive, multi-competence-enabled systems will be three novel pieces of the applied theoretical knowledge about recursivity and competences that advance the management of an IB unit as a whole and in particular that of IB ideation.

Research implications

For future research, I initially propose that the IB ideation (unit) is being managed the more successfully within its focal contexts, the more extensively the IB ideation is designed as a set of three recursive systems enabled by respective multi-competences. Moreover, the 3-system design may serve as the frame of reference for those compatible theorization initiatives vis-à-vis viable IB ideation management that interested competence-based management scholars will conduct in the future.

Practical implications

I put forth the three templates (coupled with Functions 2–3) to facilitate the enhancement of the IB ideation practices among leading, innovative firms and especially by the pioneering management of IB (ideation) units.

Abstract

Successful growth companies represent the future. Their opportunistic, customer‐responsive styles and operating practices are just what today′s turbulent, competitive environment demands. As they grow, they will become powerful forces in the economy and their successful planning and operating practices will be adopted by other aspiring organisations. The focus is upon the fast‐growing companies in Britain. Their experience over a relatively short time frame demonstrates the opportunities, threats, problems and pitfalls attached to dramatic business growth. A new set of rules which would guide companies through the necessary and predictable transitions of growth are sought. It is hoped that chief executives and strategic planning directors will use the findings, conclusions and recommendations presented to shape the future practices of their own organisations.

Abstract

Purpose

The purpose of this paper is to present the research carried out on the development of a conceptual framework termed as the reverse collaboration framework (RCF) to provide supply chain (SC) visibility and information sharing to practitioners in a reverse logistics (RL) operations.

Design/methodology/approach

The research methodology used in this research is a combination of concept mapping, and the extension of the work of other researchers (deductive approach) to develop a RCF that connects tools, techniques, systems and RL processes.

Findings

This research shows that by integrating tools, systems, tools and techniques with RL processes by means of the RCF will increase performance and productivity of a RL operations. This is demonstrated by applying the RCF to a consumer electronics business that proves that the time taken for the end to end RL operations is reduced by 20%.

Research limitations/implications

The RCF has been demonstrated with the data from a consumer electronics organisation. Literature points out that there are many different mathematical models for RL across a number of industries. Thus, at this stage, it is not clear if the RCF developed in this research will work in other industries, such as the newspaper, plastic bottles and online retailers industry where product returns are high. This research work can be extended in developing an IT solution by future researchers that can be linked to the main ERP system of an organisation.

Practical implications

SC managers can use the RCF in the extended form of an IT solution to manage the RL operations of their organisations.

Originality/value

There is a lack of research in the space of reverse collaboration in the broader field of SC management. This paper has fulfilled that gap.

Abstract

Strategic adaptation in complex environments with frequent changes must balance the search for innovative opportunistic ventures and conscious pursuit to achieve established goals and outcomes. This creates a tension between attempted efficiency gains from tight strategic controls that avoid diversion of corporate resources and the facilitation of dispersed initiatives in search for business opportunities. To assess this conundrum, the authors present an interactive strategic control model that combines planning and participative strategy-making with interactive control processes. This combination of management practices arguably creates an adaptive system that drives the upside performance outcomes from a guided adaptation of opportunistic insights. Various hypotheses are developed and tested based on survey data from among the 500 largest firms in Denmark. The results suggest a direct relationship between interactive controls, strategic planning, and participative leadership on upside performance outcomes. Moreover, the positive effect from interactive controls on the upside potential is enhanced by participative decisions.

Abstract

Purpose

This paper aims to design a multi-layer convolutional neural network (CNN) to solve biomimetic robot path planning problem.

Design/methodology/approach

At first, the convolution kernel with different scales can be obtained by using the sparse auto encoder training algorithm; the parameter of the hidden layer is a series of convolutional kernel, and the authors use these kernels to extract first-layer features. Then, the authors get the second-layer features through the max-pooling operators, which improve the invariance of the features. Finally, the authors use fully connected layers of neural networks to accomplish the path planning task.

Findings

The NAO biomimetic robot respond quickly and correctly to the dynamic environment. The simulation experiments show that the deep neural network outperforms in dynamic and static environment than the conventional method.

Originality/value

A new method of deep learning based biomimetic robot path planning is proposed. The authors designed a multi-layer CNN which includes max-pooling layer and convolutional kernel. Then, the first and second layers features can be extracted by these kernels. Finally, the authors use the sparse auto encoder training algorithm to train the CNN so as to accomplish the path planning task of NAO robot.

Abstract

With the development of the new rural construction action of beautiful industries, the problem of uncoordinated development of the rural economy and ecological protection has become increasingly prominent. Based on this, in the process of planning, design, construction and management, ecological construction technology was introduced. The planning and design of ecological recycling economy and rural greenway were studied, and the planning types of greenway in industrial villages were deeply explored. Taking the planning and construction of industrial rural greenway in Anji county as an example, the research and analysis were carried out. From the rural road, landscape space, ecology, service facilities, logo and so on, the planning was carried ou, and the greenway network of industrial villages in Anji county was constructed. Combined with practical engineering research, the scientific and rational development of rural greenway in the urban and rural construction throughout the countryn was promoted, the contradiction between urban and rural construction and ecological protection was effectively solved, and the construction of beautiful countryside was promoted.

Abstract

Purpose

In successfully meeting city and metropolitan growth, sustainable development is compulsory. Sustainability is a must-focus for any project, particularly for large and mega rail infrastructure. This paper aims to investigate to what degree social, environmental and economic factors influence the government when planning sustainable rail infrastructure projects. To respond to such a matter, this paper focuses on two Australian mega-rail projects: the South West Rail Link (SWRL) and the Mernda Rail Extension (MRE).

Design/methodology/approach

As the basis of an experimental evaluation framework strengths, weaknesses, opportunities and threats (SWOT) and factor analysis were used. These two methods were specifically selected as comparative tools for SWRL and SWRL projects, to measure their overall sustainability effect.

Findings

Using factor analysis, in the MRE, the factors of network capacity, accessibility, employment and urban planning were seen frequently throughout the case study. However, politics and economic growth had lower frequencies throughout this case study. This difference between the high-weighted factors is likely a key element that determined the SWRL to be more sustainable than the MRE. The SWOT analysis showed the strengths the MRE had over the SWRL such as resource use and waste management, and natural habitat preservation. These two analyses have shown that overall, calculating the sustainability levels of a project can be subjective, based on the conditions surrounding various analysis techniques.

Originality/value

This paper first introduces SWRL and MRE projects followed by a discussion about their overall sustainable development. Both projects go beyond the traditional megaprojects' goal of improving economic growth by developing and enhancing infrastructure. Globally, for such projects, sustainability measures are now considered alongside the goal of economic growth. Second, SWOT and factor analysis are undertaken to further evaluate the complexity of such projects. This includes their overall sustainable development vision alignment with environmental, economic and social factors.
