The purpose of the study is to improve the quality of alumina-containing sinter produced in a rotary kiln. Simulating sintering furnace assessment of technical solutions aimed at creating optimal phase composition of clinker.

The computer model of the sintering furnace is developed. Influence of characteristics of material streams on thermal processes in the furnace was considered. Balance of energy, including heat conductivity, convection and radiant heat exchange has been solved in a stable state. Between actual and calculated variables of work of the furnace, good correlation was observed.

The evaluation of the effect of increasing primary air and fuel burner extension to changes in temperature of the material. The modeling found that the most effective solution to reduce the temperature of the sinter is lengthening fuel burner to 5 m.

The model can be applied to analyze and optimize the alteration of temperatures of materials and gases in an industrial furnace under various conditions.

The article provides new information for specialists in the production of alumina. For the first time shows the influence of cooling conditions on the alumina-containing sinter quality. According to the results of computer modeling, it has been established that for creating of optimal cooling conditions of the sinter in the furnace, the length of coal burner must be not less than 5 m.

This study aims to investigate how actors’ responses to competing logics (academic and business logics) in budgetary practices in a university setting in Tanzania were shaped by state pressure, market pressure and organizational characteristics (funding certainty and changes in university ownership) and how actors’ agency was exercised in enacting competing logics.

The data for this study were collected from interviews, observations, informal discussions and document review. The data analysis processes were guided by institutional logic concepts and the role of actors’ agency.

The findings demonstrate how academic logic traditionally subsisted in a university setting in which there was funding certainty. Changes in the university’s ownership resulted in funding uncertainty. Market and state pressure increased the intensity of funding uncertainty, which supported business logic. While market logic supported the emergence of business logic, state pressure altered the balance of the competing logics. University actors responded by selective coupling and compartmentalizing where both elements of academic and business logics were enacted. While managers prioritized business logic, academics prioritized academic logic. However, the role of agency was exercised in actors’ responses, subverting both academic and business logics.

Managers should appropriately enact both elements of competing logics to avoid marginalization of some of the core university activities. In addition, profitable business ideas should be considered, identified, planned and implemented successfully. Moreover, there is a need to change the historically contingent and culturally situated environment when enacting competing logics. Furthermore, the state influence on universities should be considered to prevent unnecessary uncertainties in budgetary practices.

The paper demonstrates how selective coupling and compartmentalizing strategies were used by actors to enact both elements of competing logics in budgetary practices in a university setting. It further shows how actors’ agency influenced and subverted competing logics. The paper, thus, responds to the recent calls to investigate the influence of institutional logics on control practices, and the role of actors in strategically handling different logics in developing countries (Damayanthi and Gooneratne, 2017; Argento et al., 2020; Anessi-Pessina et al., 2016; Grossi et al., 2020). It further suggests new analysis of academic and business logics in their context.

Saudi Arabia's 2030 vision targets an increase of 34% in non-oil revenue participation in the GDP, thus the need for automation and digital transformation. The Company ER is a market leader producing high-quality dairy products in the Kingdom and is a pioneer in the production industry. The company has recently increased the capacity of its milk factory to meet its vision. An investment was made to automate the pallet handling procedures at the milk factory to provide increased production for daily consumption. The new automation transition in Company ER's milk factory provides a unique opportunity to utilize lean management tools to improve the current automated processes before commercialization.

OEE (overall equipment effectiveness) will monitor losses for different operational losses in the new automated system and indicate system improvements, with 85% as the target. Based on DMADV (design, measure, analyze, design and validate) methodology, this study analyzes the entire automated pallet handling system. It uses lean tools to identify areas for improvement, identify waste elements and propose solutions to achieve Company ER's OEE targets.

In this paper, the outcomes will be presented as documented solutions that address the losses encountered in the production system, showing a 12.8% increase in the system's OEE.

Owing the time and resource constraint, this study only involved automated pallet handling procedures in a milk production facility. Hence, the generalization of the result is slightly limited. More studies in several different processes and sectors are required.

This study provided a valuable tool for researchers for gaining deeper understanding regarding the lean manufacturing and its implementation. For practitioners, it is useful to evaluate the degree of lean manufacturing tools in their material handling systems.

This study is the first attempt to develop lean manufacturing constructs for evaluating the automated pallet handling procedures in a milk production facility.

This study aims to identify which elements of the vending marketing mix are the main sources of competitive advantage for the industry, how they impact vending profitability, and what are their related synergistic effects.

A full factorial experiment was developed to determine the effect of eight marketing mix scenarios on the profitability of a new vending channel in a French university library and assess the synergistic effects among three elements of a marketing mix (i.e. product quality, payment system, internal location) identified in a focus group as new sources of industry competitive advantage.

Although the main effects of product quality and payment system were weak-to-modest and insignificant, their interaction effect significantly impacted the daily net profit of the vending channel and generated the highest net synergy. The results partially challenge the marketing synergy axiom as internal location separately had a stronger impact on profitability than product quality and higher-order interaction effects do not necessarily translate into higher synergistic effects.

This research was conducted in a real-life setting and has its limitations, which future researchers can overcome by extending the temporal, geographic and product scope of the study.

The distinction that we introduced between gross and net synergy allowed us to partially challenge the prevailing marketing mix assumption that synergy is always positive (i.e. that a vending retailer can achieve synergy by selecting a combination of marketing mix elements instead of relying on them separately). Moreover, by demonstrating that marketing synergy is not a uni- but a bi-dimensional concept, we provide vending retailers with a better methodological understanding of why they may have already fallen into the synergy trap and how to avoid it in the future.
