Title: Automated treatment planning optimization for LGK Perfexion

Abstract

In radiation therapy for cancer treatment, inverse planning approaches—

wherein optimization tools are used to automatically generate treatments—are

gaining in both popularity and clinical acceptance. While intensity modulated

radiation therapy has been the primary focus of optimization-based inverse

planning research in the literature, technological advances in the delivery of

stereotactic radiosurgery mean that radiosurgery treatments can now also

benefit from optimization-based treatment planning. We investigate several

optimization approaches for the Leksell Gamma Knife Perfexion radiosurgery

treatment device (Elekta AB, Stockholm, Sweden) and find that optimization

can improve on clinical deliveries as well as enable new treatment possibilities

for Perfexion, including continuous delivery and homogeneous dosages.

Title: Location-Routing Problems with Economies of Scale

Abstract

The location-routing problem aims to select the sites at which facilities

(Distribution Centers) will be open, assign customers to those facilities, and

design vehicle routes from there to respective customers. The objective is

minimal total cost. For the “standard” location-routing problem, that total cost

includes (just) the fixed costs to open DCs plus the transportation costs from

facilities to customers. In this paper, we also consider the variable cost of

facilities’ operations. Two forms of variable cost are proposed. One is a linear

cost function with a constant operating cost per unit; the other employs a

concave function of total throughput at each DC. The latter is studied because

larger facilities may permit the use of enhanced technology, hence possible

achievement of economies of scale.

Following preliminary tests of several metaheuristic solution methods, we

employed a genetic algorithm with ant colony optimization. Computational

experiments of the model without variable cost are performed on two

published data sets. Then extensive testing is done on modified data sets: for

cases with operating cost but without economies of scale, and for other cases

when scale economies are present. We analyze the influence of economies of

scale, and study how parameter values affect those economies. Then we

carefully exhibit the tradeoffs between facility operating costs and

transportation costs. Conclusions are drawn and further research is suggested.

Title: Healthcare Engineering: Quantitative Decision Support Models for the

Healthcare Industry

Abstract

Health Care is the number one industry in North America; bigger than automotive,

telecommunications or steel. Estimated total spending in 2016 in Canada was $228

billion or 11% of the GDP. Spending in the U.S. in 2015 was $3.2 trillion dollars US 17.6%

of the GDP. In 2015, Canada spent $5,543 per capita while the U.S. spent $11,126(CN).

Health care systems all over the world are in the midst of a serious financial crisis, and

the situation will likely get worse in the next few years. Demand is going up as the

population ages, and costs are increasing as the drugs and technologies continue to get

more complex and expensive.

Of course, it would help if there were more money available. However, I also firmly

believe that the health care industry could be run a lot more efficiently. Dr. Don Berwick

(former CEO of the U.S. Center for Medicare/Medicaid) claims that, in the U.S., 30% of

the cost of healthcare is waste. I suspect the same is true in Canada. Industrial Engineers

are helping the health care industry improve quality, reduce costs, improve effectiveness

and increase efficiency. Many of the concepts that have been used to manage supply

chains in other industries are slowly finding their way into healthcare. In this talk, I will

describe a few examples including strategic issues (health human resource planning),

tactical questions (wait list management) and operational problems (outpatient clinic

scheduling).

Title: OR Applications In Preventive Healthcare

Abstract

Preventive health care is a critical part of the national health systems that

includes the interventions towards preventing infectious/chronic diseases or

conditions. These interventions includes vaccination for infectious diseases,

preventive cancer screening (e.g., for colorectal cancer), public health measures

for limiting HIV spread and tobacco usage, etc. My talk will review some of the

challenging medical decision making and healthcare delivery problems related

to particular preventive healthcare problems. I will specifically focus on

vaccination for infectious diseases and cancer screening applications to discuss

how OR can provide insights for the controversial policy issues in this field.

Title: Optimal Lighting Control with Pervasive Sensing

Abstract

Most current daylight harvesting lighting systems measure lighting levels at the

luminaires, rather than at the work surface. Instead, we propose a system that

measures illuminance directly from an array of sensors embedded in the work

surface. Periodic illuminance measurements are performed unobtrusively by

careful scheduling of luminaire dimming times. We use a linear-programming-

based control algorithm that minimizes the power consumption while

dynamically accommodating heterogeneous illuminance requirements and

changes in occupancy. We evaluate the performance of our control algorithm in

a set of test scenarios and in our lab, and find that our system can reduce

energy consumption, compared to typical operating conditions by about 25%.

Title: Going, going, …., gone with probability p: A Stochastic Process

Approach to Auctions

Abstract

Auctions and competitive bidding are interesting commercial phenomena that

date back to the ancient civilizations. It is has historically been used extensively

as a sales mechanism in both Business-to-Business and Business-to-Consumer

markets. More recently, due to the rise of the internet, auctions have also

become commonplace in Consumer-to-Consumer markets. Despite auction’s

rich history as an economic mechanism, the theoretical Economics based

analysis only took shape with the development of modern Game Theory. It is

regrettably lesser known that the analysis of auctions also has a long standing

Operations Research tradition. In fact, the first PhD in Operations Research

(1957) was based on auction analysis.

In this talk I will cover three topics: (1) a brief history of auctions and auction

theory; (2) how auctions can be viewed and analyzed as a stochastic process;

and (3) some recent results on Shubik’s Dollar Auction (work co-authored with

Charles Zhang, Dept. Economics, UWO).

Title: Inventory Optimization for Fulfillment Integration in Omnichannel

Retailing

Abstract

With ecommerce growing at a rapid pace compared to traditional retail, many

brick-and- mortar firms are supporting their online growth through an

omnichannel approach, which integrates inventories across multiple channels.

We analyze the inventory optimization of three such omnichannel fulfillment

systems for a retailer facing two demand streams (online and in-store). The

systems differ in the level of fulfillment integration, ranging from no

integration (separate fulfillment center for online orders), to partial integration

(online orders fulfilled from nearest stores) and full integration (online orders

fulfilled from nearest stores, but in case of stockouts, can be fulfilled from any

store). We obtain optimal order-up-to quantities for the analytical models in

the two-store, single-period setting. We then extend the models to a

generalized multi-store setting, which includes a network of traditional brick-

and- mortar stores, omnichannel stores and online fulfillment centers. We

develop a simple heuristic for the fully-integrated model, and augment our

analysis with a realistic numerical study for networks embedded in the

mainland US, which demonstrates the efficacy of our heuristic. The talk will

close with an overview of other research directions in the space of

ecommerce/omnichannel operations.
