A bottom-up role of information asymmetry: opening the black-box of firms’ resource allocation mechanism

Purpose Drawing on the concept of resource-based theory of the firm; the purpose of this study is to analyze the influence of firms’ strategic approaches on the firm performance via indirect effect using a multilevel, bottom-up approach. Design/methodology/approach Using the survey method, the present study obtains data from 104 diversified manufacturing firms and analyzes the bottom-up effect of firms’ strategic approach on efficient resource allocation using Mplus. Findings Given the prevailing conditions, the study found that the motive of most firms is growth rather than risk mitigation or collaboration in the manufacturing sector of Pakistan. Furthermore, the study found that the bottom-level employees’ information asymmetry has a significant impact on the strategic resource allocation decision, which can lead to resource allocation inefficiency. Research limitations/implications Despite making a unique contribution, the present study has few limitations requiring researchers’ attention to in the forthcoming. These include a low amount of data, self-reporting technique and failure to include all the possible reason that could cause resource allocation inefficiency. Practical implications The present research has potential applications for managers of the manufacturing industry. First, the study alerts managers about the challenges of resource allocation. At the same time, this study provides critical implication for managing bottom-level employees. Originality/value The current study has made a sizable impression in the literature of resource-based theory of the firm by recommending a model that augments the theoretical foundation of strategic management of the firm. So, closely considering these insights would be helping for the firms for allocating resources efficiently in the manufacturing industry.

A Job-Shop Scheduling Problem with Bidirectional Circular Precedence Constraints

This paper introduces a job-shop scheduling problem (JSP) with bidirectional circular precedence constraints, called BCJSP. In the problem, each job can be started from any operation and continued by its remaining operations in a circular precedence-relation chain via either a clockwise or counterclockwise direction. To solve BCJSP, this paper proposes a multilevel metaheuristic consisting of top-, middle-, and bottom-level algorithms. The top- and middle-level algorithms are population-based metaheuristics, while the bottom-level algorithm is a local search algorithm. The top-level algorithm basically controls a start operation and an operation-precedence-relation direction of each job, so that BCJSP becomes a JSP instance that is a subproblem of BCJSP. Moreover, the top-level algorithm can also be used to control input parameters of the middle-level algorithm, as an optional extra function. The middle-level algorithm controls input parameters of the bottom-level algorithm, and the bottom-level algorithm then solves the BCJSP’s subproblem. The middle-level algorithm evolves the bottom-level algorithm’s parameter values by using feedback from the bottom-level algorithm. Likewise, the top-level algorithm evolves the start operations, the operation-precedence-relation directions, and the middle-level algorithm’s parameter values by using feedback from the middle-level algorithm. Performance of two variants of the multilevel metaheuristic (i.e., with and without the mentioned extra function) was evaluated on BCJSP instances modified from well-known JSP instances. The variant with the extra function performs significantly better in number than the other. The existing JSP-solving algorithms can also solve BCJSP; however, their results on BCJSP are clearly worse than those of the two variants of the multilevel metaheuristic.

The on-orbit mission analysis of OTV based on DoDAF

Purpose The purpose of this paper is to improve the efficiency of on-orbit operations through the top-level task design based on DoDAF. Based on the existing upper stage rocket technology, orbit transfer vehicles (OTVs) have developed rapidly in recent years. However, the lack of decision guidance based on overall task analysis requires integrating top-level analysis and bottom-level execution to achieve the smooth development of full-process tasks. Design/methodology/approach Using the Department of Defense Architecture Framework (DoDAF) as a reference, this paper performs the top-level mission analysis modeling of the on-orbit rendezvous and capture of the OTV. Moreover, the typical operational view products are obtained, and the cooperative relations among the mission requirements, the system requirements, and the functional requirements are also analyzed. Findings The results show that the attitude of the OTV changes violently during the maneuver and rendezvous phases. In addition, the view products can be optimized based on the results. Originality/value The proposed DoDAF-based on-orbit task integration analysis method achieves the effective fusion of high-level analysis and bottom-level execution of OTV on-orbit rendezvous and capture task through the top-level task modeling, operation view generation and task relationship analysis. According to the requirements and constraints of the on-orbit rendezvous and capture task, the control instructions of the vehicle are efficiently generated under the DoDAF framework.

Comparative analysis of SOFC-MGT top-level and new bottom-level system performance

In order to make the SOFC-MGT system more widely used, the mathematical simulation models of the SOFC-MGT top-level circulatory system and the new bottom circulatory system were first established, and then the performance of the two systems was analyzed and compared using Matlab/Simulink simulation software. The research results show that the output performance of the SOFC-MGT top-level circulation system is due to the new bottom-level circulation system, and the stack output performance of the two systems is not much different.

Research on displacement prediction of shield tunneling through existing tunnel based on LSSVM

The construction scale of the shield tunnel underpass is expanding day by day. In order to study the safety influence and deformation control of the shield tunnel underpass on the existing tunnel, the LSSVM model is established. Based on the collected soil storage pressure, foam volume, simultaneous grouting volume and other six shield construction parameters and corresponding sample data of the tunnel bottom displacement, the horizontal displacement and settlement displacement of the existing tunnel bottom caused by the approach construction are predicted. Taking a subway project as an example, the research results show that the prediction model of shield tunneling under the existing tunnel bottom level and settlement displacement has strong generalization ability and rapid and accurate prediction effect. This method can provide reference for similar projects.

BALANCED GIVE AND TAKE — AN EMPIRICAL STUDY ON THE SURVIVAL OF CORPORATE INCUBATORS

Many companies have created corporate incubators to deal with the increasing pace of innovation and to foster innovation activities beyond their current business. Since these corporate incubators demand considerable resources, the parent companies continuously evaluate the incubators’ performance and then decide on their survival. This decision depends on the balance between incubator’s contributions and the hosting company’s financial investment (top-level), while the incubator’s contributions again depend on the balance between incubator investment and the supported new business contributions (bottom-level). We apply the Barnard-Simon theory of organisational equilibrium to investigate the resource flow balance on both levels and to predict the resulting incubators’ performance, which determines their future survival. The analysis is based on a sample of corporate incubators surveyed in 2019. Results show that incubators with a top-level equilibrium and a bottom-level disequilibrium perform better. These counterintuitive yet insightful results are discussed in detail.
