A comprehensive test method for inline flame arresters

The certification test standards that presently exist for flame arresters are highly inadequate for inline applications. A proper flame arrester test method should ensure that a unit will work with any flame front conditions that it could be exposed to in actual use. When evaluating flame arrester performance, it is just as dangerous to neglect deflagration testing as detonation testing. The comprehensive inline flame arrester test method outlined here involves exposing a unit to the entire flame propagation pressure spectrum. This includes low, medium and high pressure deflagrations as well as overdriven and stable detonations. The test method also takes into account the following factors: flow restriction on the protected side of the flame arrester, flame propagation through a flowing gas, initial system pressure and temperature, and specified gas mixture. Flow restriction on the protected side of the flame arrester has a very significant effect on performance and has not previously been given consideration in flame arrester testing. Besides moving flame front test, endurance burn testing and hydrostatic pressure testing are also discussed here. Major regulatory organizations have recently adopted these findings as the basis for new standards proposed to cover an inline flame arrester test method.

A method for determining the flammable limits of gases in a spherical vessel

The current method for determining the flammable limits for a gas in a closed spherical vessel is based on a specification of the maximum pressure increase during the combustion, usually from 5 to 10% of the initial ambient pressure. This approach is completely arbitrary and is not fundamentally based. For most hydrocarbons this pressure boundary and hence the flammable limits are easy to determine experimentally since an abrupt pressure drop occurs at the flammable limits as the fuel concentration in air is adjusted. However, for some species, particularly hydrogen mixed with air, the drop in maximum combustion pressure is not very abrupt and the fuel concentration can range several percentage points depending on the arbitrary criterion used for the flammable limits. This article will discuss a new approach for determining the flammable limits for a gas in a spherical vessel. The approach is based on the maximum second derivative of pressure rise. The second derivative is indicative of an acceleration of the combustion process and is, hence, fundamentally based. Furthermore, we have identified a new approach to determine the downward propagating flammable limits based on the combustion time, that is, the time that the gas actually burns in the vessel. Experimental data for methane and hydrogen show that the second derivative flammable limit criterion produces slightly conservative values for combustion in air. Visual inspection of the combustion during the tests showed that no visual combustion was observed at the second derivative criterion. For methane, the second derivative criterion resulted in a flammable range in air from 4.6 to 15.8% methane. For hydrogen these limits are 3.6–75.2%. We believe that this method will provide a much more fundamentally based method to determine both the upper and lower flammable limits of upward flame propagation and also provide a means to determine the downward propagation limits in a spherical combustion vessel. © 2009 American Institute of Chemical Engineers Process Saf Prog, 2009     

Decentralized control of cooperative and autonomous agents for solving the distributed resource allocation problem

This paper focuses on the decision-making mechanism of coordination protocol for a multi-agent system in collaborative, distributed environment requiring resource allocation solutions. The model of distributed collaboration network (DCN) for distributed resource allocation is developed. The use of monitored viability of each agent as a feedback for the agent's reflexivity and goal adjustment mechanisms during the coordination process is introduced. Question: Will (can) a multi-agent system, as a whole, achieve efficient resource allocations, when each agent makes independent decisions, adjusted by feedback of its own viability measure to maximize its own goal based on limited information about the entire system? To investigate this question, experiments were conducted by using the parallel simulator TIE/Protocol to model the DCN and multi-agent system behavior.     

A binary solution method for the multi-product newsboy problem with budget constraint

Multi-product newsboy problem (MPNP) with budget constraint is a classical inventory control/management problem. However, solution methods for MPNP under general demand distributions are limited in the current literature. In this paper, by analyzing properties of the optimal solution to the MPNP with a budget constraint, we develop a solution algorithm for the constrained MPNP. The proposed algorithm is binary in nature, and is applicable to general types of demand distribution functions, discrete as well as continuous. For continuous demand distribution function, our approach can obtain the optimal or near optimal solution to the constrained MPNP with polynomial computation complexity of the o(n) order. On the other hand, for discrete demand distribution functions, it can effectively provide good approximate solution. Numerical experiments are presented to show the performance of our method.     

A decision method for supplier selection in multi-service outsourcing

Although supplier selection in multi-service outsourcing is a very important decision problem, research concerning this issue is still relatively scarce. This paper proposes a decision method for selecting a pool of suppliers for the provision of different service process/product elements. It pioneers the use of collaborative utility between partner firms for supplier selection. A multi-objective model is built to select desired suppliers. This model is proved to be NP-hard, so we develop a multi-objective algorithm based on Tabu search for solving it. We then use an example to show the applicability of the proposed model and algorithm. Extensive computational experiments are also conducted to further test the performance of the proposed algorithm.

A method for identifying and assessing key customer group needs

This paper presents a methodology for identifying and weighing the importance of product attributes used by a key customer group of a company. A central feature of the technique is the introduction of a new concept: competition factors (CF). These factors address the influence of substitute products in the specific product attributes that a customer group considers. A better knowledge of substitute products can surface previously hidden or latent customer needs. CF allow dealing with this problem, providing a powerful tool for market-oriented businesses that seek to understand customers' expressed and latent needs. The wood products industry and architects are used to illustrate the technique.     

A fast method for analysing and improving complex software processes

This paper presents a simple, fast method (or management tool) for the analysis and improvement of software-intensive complex products and systems (CoPS) called software analysis-software improvement (SA-SI). The tool relies on outside intervention, rapid data collection and structured in-company workshops. The distinctive feature of the method is that it focuses on the 'soft', human side of the software development process and examines and compares formal (or rational) processes ('what should be') with real, actual practices ('what is'), in order to identify problems, their causes and strategies for improvement. The tool complements existing formal approaches by delivering a 'bottom up', grass roots, practitioner view of real processes in action. The purpose of SA-SI is to help overcome the severe problems of measuring, analysing and improving performance in large scale, complex software projects. An illustrative case example (Company X) is used to show how the tool is applied and how it confronts the problem of actual/real processes differing from ideal/formal processes. It also shows how SA-SI is used to identify process 'hot spots'(severe problems), analyse their causes and identify solutions. The paper provides guidance on typical problems encountered in running SA-SI and how to overcome them. It also shows how the tool has been modified and extended to deal with other complex domains and innovation management issues. Although SA-SI cannot be a substitute for a change programme, it can play a useful part in complementing ongoing improvement activities. From a research perspective, the method helps link up studies from the organisational development and software fields and assists in 'closing the loop' between innovation research and business practice.

Disruption management in distributed enterprises: A multi-agent modelling and simulation of cooperative recovery behaviours

Disruption management in industrial areas consists in dealing with unanticipated events that get the plans deviate from their intended course. The solution results from the design and the maintenance of an operating mode ensuring a relevant deployment of individual recovery behaviours.The paper proposes an approach to minimize the impact of disrupting events on the whole system. It is based on an analysis of disrupting events and the characterization of the recovery process, and on a cooperative repair method for distributed industrial systems. This method is based on a cooperative distributed problem solving approach supported by a multi-agent system framework.
