Nexterra Systems Corp. designs and develops gasification systems that convert waste biomass into heat andpower. One of their projects was in collaboration with the University of British Columbia (UBC), where abiomass gasification system with 6 MW thermal energy capacity was installed. In order to achieve its GHGreduction objectives by 2020, UBC is considering adding a new bioenergy system to expand the heatproduction on campus by about 3 times. The installation of the new system would require more biomass, whilebiomass storage capacity would be reduced. Reliability of biomass supply is a key issue to provide heat oncampus. While the total annual biomass may be sufficient for bioenergy production, the variability in supplychain may bring shortage in daily, weekly or monthly delivery of biomass. In order to ensure the smoothoperation of the new biomass system, the right quantity of wood biomass with the desired quality at theminimum cost must be delivered to UBC every day. Therefore, it is essential to perform supply chain riskassessment of the gasification and new systems at UBC and optimize the supply chain to minimize thedelivered cost. The objective of this collaborative project with Nexterra is to analyze and perform a riskassessment of the supply chain of wood biomass at UBC while considering the quality, quantity and cost ofdelivered biomass. Based on this information, the minimum storage volume required for the new system willbe assessed. Then, a mathematical programming model will be developed to determine the optimum storagesize on campus and flow of biomass from the supplier while minimizing the total cost of the supply chain. Inaddition to helping Nexterra, the proposed project will present a new insight to UBC which will help them intheir deliberation concerning their high capital investment. The results of this project will be useful inachieving UBC's ambitious GHG emission reduction targets. Emission reduction will benefit UBC, BritishColumbia and Canada to move towards sustainable communities and their plans to mitigate climate change.

Nexterra系统公司设计和开发气化系统，将废弃的生物质转化为热能和电能。他们的一个项目是与不列颠哥伦比亚省大学（UBC）合作，在那里安装了6兆瓦热能容量的生物质气化系统。为了实现到2020年的温室气体减排目标，UBC正在考虑增加一个新的生物能源系统，将校园的热量生产扩大约3倍。新系统的安装将需要更多的生物量，而生物量储存能力将减少。生物质供热的可靠性是校园供热的关键问题。虽然每年的总生物量可能足以用于生物能源生产，但供应链的可变性可能导致每日、每周或每月交付的生物量短缺。为了确保新的生物质系统的顺利运行，每天必须以最低的成本向UBC输送适量的木材生物质。因此，对UBC气化系统和新系统进行供应链风险评估，优化供应链以降低交付成本是非常必要的。与Nexterra合作的这个项目的目的是分析和执行UBC木材生物质供应链的风险评估，同时考虑交付生物质的质量，数量和成本。根据这些信息，将评估新系统所需的最低存储容量。然后，将开发一个数学规划模型，以确定最佳的storagesize在校园和生物质从供应商的流量，同时最大限度地减少供应链的总成本。除了帮助Nexterra，拟议的项目将提出一个新的见解，以UBC这将有助于他们在他们的审议有关他们的高资本投资。该项目的结果将有助于实现UBC雄心勃勃的温室气体减排目标。减排将有利于UBC，BritishColumbia和加拿大走向可持续社区及其减缓气候变化的计划。
