Abstract

Purpose

This paper aims to address a fundamental problem related to the interaction of rule‐based autonomous agents in pervasive and intelligent environments. Some rules of behaviour can lead a multi‐agent system to display unwanted periodic behaviour, such as networked appliances cycling on and off.

Design/methodology/approach

The paper presents a framework called interaction networks (INs) as a tool to describe and analyse this phenomena. In support of this, and as an aid to the visualisation and understanding of the temporal evolution of agent states, a graphical multi‐dimensional model (MDM) is offered. An instability prevention system (INPRES) based in identifying and locking network nodes is described.

Findings

Both IN, MDM and INPRES enable system designers to identify and prevent cyclic instability. The effectiveness of the approach is evaluated using both simulated and physical implementations.

Research limitations/implications

The problem of cyclic instability is strongly related to the number of cycles in the IN associated. It is postulated that high coupling and high number of cycles contributes to the system to self‐lock; however, more research is needed in this direction.

Practical implications

The MDM, interaction benchmark, IN theory, INPRES and intelligent locking offer a practical solution to the problem of cyclic behaviour.

Originality/value

Before this work there was no framework for analysing and eliminating the problem of cyclic instability in rule‐based multi‐agent systems.

Abstract

This chapter explores the transformative potential of green innovation within the informal manufacturing sector of Bangladesh. It presents an empirical analysis aimed at uncovering the economic benefits derived from integrating green innovation practices into informal enterprises. Through a comprehensive field investigation, the study highlights how green initiatives can act as catalysts for enhancing economic performance, promoting sustainability, and improving competitiveness in a market increasingly conscious of environmental impact. The research adopts a qualitative methodology, engaging with a variety of stakeholders including small-scale manufacturers, local entrepreneurs, and policy-makers within the Comilla district of Bangladesh. It identifies key challenges and opportunities faced by informal enterprises in adopting green technologies and practices. The findings suggest that, despite existing barriers, there is a notable enthusiasm and potential for green innovation as a means to achieve economic growth and environmental sustainability simultaneously. Key insights reveal the importance of supportive policies, access to green finance, and the need for awareness and training programs for the needs of the informal sector. This chapter argues that fostering a conducive ecosystem for green innovation not only contributes to the economic enhancement of informal manufacturers but also aligns with broader national goals of sustainable development. This analysis contributes to the discourse on environmental sustainability and economic development by providing evidence-based recommendations for integrating green innovation into the informal manufacturing sector of Bangladesh, offering a scalable model for similar economies globally.

Abstract

Purpose

This study estimates the land footprint, nutrients and monetary value of persimmon loss in Brazil, and also consolidated the methodological approach for assessing resources related to food loss.

Design/methodology/approach

It uses data on the harvested area, production, production loss and production value of persimmon in Brazil from 2014 to 2019. The persimmon loss in Brazil was converted into macro- and micronutrients, land use and monetary value.

Findings

The average annual production loss, loss production value and land footprint of persimmon are 35,100 tons, US$12m  and 1,673 hectares, respectively. Persimmon loss represents the average loss per year of 6.6bn grams of carbohydrates, 1.6bn grams of food fibers, 7.2bn milligrams of vitamin C, 41.8bn micrograms of vitamin A, 4.5bn milligrams of calcium and 54.8bn milligrams of potassium. These nutrients have the potential to meet the nutritional daily needs of approximately 135,000, 176,000 people, 270,000, 164,000, 12,000 and 32m, respectively.

Practical implications

Through (1) research and innovation; (2) infrastructure development; (3) training and education; (4) collaboration and networking; and (5) market diversification and value addition, people can increase persimmon shelf life, reduce postharvest losses and create a resilient environment for small persimmon farmers. This approach promotes sustainability in the agri-food system and empowers stakeholders.

Originality/value

This investigation helps to understand the value of food loss, considering the use of natural resources, as well as the loss of nutrients and monetary value.
