Optimal stack layout in a sea container terminal with automated lifting vehicles

Akash Gupta, Debjit Roy, Rene de Koster, and Sampanna Parhi

International Journal of Production Research

Container terminal performance is largely determined by its design decisions, which include the number and type of quay cranes, stack cranes, transport vehicles, vehicle travel path and stack layout. We investigate the orientation of the stack layout (parallel or perpendicular to the quayside) on the throughput time performance of the terminals. Previous studies in this area typically use deterministic optimisation, and a few studies use probabilistic travel times and simulation to analyse the effect of stack layout on terminal throughput times. In this research, we capture the stochasticity with an integrated queuing network modelling approach to analyse the performance of container terminals with parallel stack layout using automated lifting vehicles. Using this analytical model, we investigate 1008 parallel stack layout configurations on throughput times and determine the optimal stack layout configuration. We find that, assuming an identical width of the internal transport area, container terminals with parallel stack layout perform better (from 4–12% in terms of container throughput times) than terminals with a perpendicular stack layout.

This place is not the same anymore; temps are coming in

Saikat Chakraborty

Business Review India

As organisations increasingly rely on temporary work arrangements, there is a significant rise in the proportion of workers in part-time, contractual, fixed tenure, and other such labour engagements. Due to the difference between the employment relationships of temporary and permanent workers, corporations often design separate control mechanisms for these two worker groups. This paper argues that organisational control of workers extensively shapes their organisational communication. Communication as constitutive of organisation (CCO) research says that the interaction between members and objects plays a vital role in constructing ‘communication yielding organising.’ The emergent organisation rests on the negotiations of conversations and texts which carry the ongoing organisational communication. Workplaces in which the workforce composition is shifting from permanent workers to a mixture of permanent and temporary workers gradually realise pertinent changes in their conversations and texts, which as carriers of organisational communication constitutes how the organisation emerges as well.

Customer dependence and customer loyalty in traditional and modern format stores

Hari Govind Mishra, Piyush Kumar Sinha, and Surabhi Kaul

Journal of Indian Business Research

Purpose

The purpose of this paper is to examine the relationship between customer loyalty and customer dependence in the context of modern format and traditional format stores. In the process, the role of switching cost and trust in this relationship has been explored.

Design/methodology/approach

Building on the literature, the authors have postulated a conceptual model and formulated relevant hypotheses. Quantitative methodology is applied with previously established. The data were collected through convenient sampling. Methods like Factor analysis, cross-tab and regression analysis have been used.

Findings

The findings indicate a significant relationship between customer loyalty and customer dependence. Switching cost and trust have been found to have a moderating effect over the relationship in both modern and traditional environments.

Research limitations/implications

The limitation is the restriction to the Jammu context. The studies have brought about the difference in attitudinal and behavioural loyalty. Future research can be carried out on the role of dependence in explaining and strengthening this relationship.

Originality/value

The present study provides an insight into for the customer loyalty and customer dependence in the context of modern and traditional retail formats.

Multilevel analysis of ambidexterity and tagging of specialised projects in project-based information technology firms

Srihari Suresh Sohani and Manjari Singh

International Journal of Operations & Production Management

Purpose

The purpose of this paper is to understand the expression of ambidexterity at the “between” projects level as well as the “within” project level in project-based information technology firms (PBITF). The research also provides a framework for the classification of specialised projects. This classification is essential to clarify the level of attention the project will receive with respect to the appropriation of resources and the requisite management bandwidth.

Design/methodology/approach

This paper draws on a nine-month long field-based qualitative study and ensures a rigorous triangulation of the findings through an analysis of archival data and actual project artefacts.

Findings

The authors bring forth three critical implications for practice. First, strategizing ambidexterity at the level of “between” projects and “within” projects is heavily dependent on the interaction among distributed actors and partners. Second, routines and actions to deal with manpower constraints are completely different at these two levels. Lastly, the classification framework of specialised projects proposed here should enable firms to appropriately apportion resources to engagements that are strategic in nature.

Originality/value

The study extends the concept of ambidexterity to the “within” project level and finds it relevant at the lowest level in the project-based structure. Also, the framework for the classification of specialised projects that is provided will assist decision makers in PBIT firms to decide the organisational response to such projects.

Human resource planning as a strategic function: Biases in forecasting judgement

Manjari Singh and Jatinder Kumar Jha

International Journal of Strategic Decision Sciences

This paper explores the strategic importance of human resource (HR) planning and the various techniques employed by organizations to attract talent and thus to gain a competitive edge. In this paper, the authors have tried to explore the various biases that come into play when supervisors forecast for human resources. Backed by research, the paper recommends the integration of line managers with HR managers and their participations in strategic planning to enable the HR managers to gain valuable insights for HR planning. The paper further suggests that though biases cannot be ruled out completely but they can be controlled by providing relevant training to the HR and line managers to forecast dynamics. Further, the judgement of the line managers could be complemented with other forecasting techniques to make the process more reliable.

Rough information set and its applications in decision making

Manish Aggarwal

IEEE Transactions on Fuzzy Systems

The decision making in the real world is inevitably characterized with vagueness, and imprecision due to incomplete knowledge. To this end, we combine the information set with the rough set theory to represent both the vagueness and imprecision at the same time. We term the proposed structure as rough information set that has information sets based on fuzzy equivalence relations as its building blocks. The usefulness of the proposed structure is demonstrated through a case study in credit scoring analysis, and a biometrics application on knuckle-based recognition.

Adaptive linguistic weighted aggregation operators in multi-criteria decision making

Manish Aggarwal

Applied Soft Computing

In this paper, we propose new aggregation operators for multi-criteria decision making under linguistic settings. The proposed operators are based on two sets of criteria weights. Besides the primary conventional criteria weights, we introduce a method to deduce secondary criteria weights from the criteria evaluations, which reflect the role of the different criteria in discriminating among the alternatives. The properties of the proposed operators are investigated. An approach for the application of the said operators in a group multi-criteria decision making problem is presented. Following the same, the proposed operators are applied in a case study on supplier selection. The empirical validation of the proposed operators is performed on a set of 12 real datasets.

Constitutional mandate and judicial initiatives influencing Water, Sanitation and Hygiene (WASH) programmes in India

M P Ram Mohan and Anvita Dulluri

Journal of Water Sanitation and Hygiene for Development

This paper undertakes a thorough review of the legislative and policy framework of water supply and sanitation in India within the larger backdrop of the universal affirmation of right to water and sanitation under the UN WASH initiatives, first articulated under the Millennium Development Goals (MDGs). Recognizing the proactive role played by the Indian judiciary in this regard, the paper examines various patterns of judicial reasoning in realising the right to water and sanitation as Constitutional rights of citizens. The paper observes that through a consistent ‘rights-based’ approach, the Indian judiciary has systematically articulated and achieved the objectives of the UN WASH initiatives long before they were spelled out under the MDGs. The paper highlights the need for the Government to recognise and incorporate judicial insights in implementing developmental projects under the WASH initiatives.
