...Case Study Arc Solutions Provides a centrally controlled operator center solution to Heffernan Group s o l u t i o n s The Challenges With an overall emphasis on customer service excellence, communication both internally and with customers has always been a key element to the success of the company. Whilst effective, this solution was not ideal as the company’s main aim was to ensure that all customers were dealt with personally by the operators. Having separate telephone systems serving each site also provided challenges, with the infrastructure being inflexible and a high systems management overhead. It also meant that operators had to be deployed to cope with the incoming traffic of that particular branch office, with no capability to share the load with other offices in busier times. Heffernan therefore decided to move to a single centralized communications platform, serving all sites. They chose Cisco Unified Communications technology as it delivered the power, flexibility and reliability to serve the whole business and its customers, both now and in the future. Whilst this provided an excellent platform for unifying communications across the enterprise, Profile Heffernan Insurance Brokers, formed in 1988, is one of the largest independent insurance brokerage firms in the United States.

...true sample size of only 362 logs, as data for logs # 30, 123, and 127 are missing from his report. He videotaped 3 operators, April, Sid, and Jim, marking the logs, how each log was broken down and the degree to which the cants were properly centered. Gene then did a comparison of what the cost was of the log in its current condition (actual value), to what would have been the correct value of the log if the cut had been accurate (potential value). This allowed him to see the potential revenue that Welco Lumber Company is losing out on their business (profit gain). Question 1: How much profit is lost on imperfect board cuts? During the processing of 362 logs, it was found that exactly half (181) or fifty percent were processed without error. The remaining 181 logs were found to have undergone some type of error in the breakdown process—excessive log breakdown, off center cant, reduced value cut. As a result, the Welco Lumber Company missed out on $735.14 in potential profit. Taking these results one step further, the potential amount of money lost on each of the 181 logs with errors was broken down into ranges of value lost as shown below. From the graph we can see the nominal value that was lost the most fell between the $1.51 to $4.50 ranges. Question 2: How does performance vary among operators? Below is a table that shows the analysis of each operator by log size, log volume, and with the monetary values of actual versus potential values. We can see that April produces...

...Programming Final 1. The case structure lets the value of a variable or an expression determine which path of execution the program will take. It’s a multiple alternative decision structure that allows you to test the value of a variable or an expression and then use that value to determin which statement to execute. 2. The AND operator takes two Boolean expressions as operands and creates a compound Boolean expression that is true only when both expressions are true. True AND True = True 3. The OR operator takes two Boolean expressions as operands and creates a compound Boolean expression that is true when either of the sub expressions is true. True OR False = True 4. The NOT operator is a unary operator that takes a Boolean expression as its operand an reverses its logical value. The Not operator reverses the truth of its operand. If it is applied to an expression that is true the operator returns false. If it is applied to an expression that is false it returns True. Not true = False, Not false = True 5. Flow chart 6.

...day operations • The operators receive calls from the salesmen in the field using operating consoles. A green light indicates an incoming call. • Calls are assigned sequentially to waiting operators • The stock number is determined and the relevant information such as stock level, delivery times and price is provided and relayed to the salesmen • At the end of the call the green light would extinguish itself and the operator will wait for another call. A visit from the Vice President indicating falling sales, high error rate and number of delays currently being experienced by the salesmen caused Eric to devise a program to deal with these issues. Eric’s program however was met with opposition from both employees and supervisors. Although the plan appeared to have worked for a few days, it failed to motivate employees and had a spiral effect which impacted on his relationship with supervisors and the general staff. (ii) KIPSY Kipsy applied for a job at the company because she heard it was great place to work, and since it was rapidly expanding, that meant she can move up the corporate ladder. Her excitement quickly changed to boredom as the job became monotonous. She was frustrated also due to the fact that there appears to be very little chance for advancement for operators. As a result, more and more employees were leaving the office. The possibility also exists that the entire operation will be automated which meant the operators will be laid off. Kipsy...

...Journal of Arti cial Intelligence Research 7 (1997) 83-124 Submitted 6/97; published 9/97 Towards Flexible Teamwork Milind Tambe Information Sciences Institute and Computer Science Department University of Southern California 4676 Admiralty Way Marina del Rey, CA 90292, USA tambe@isi.edu Many AI researchers are today striving to build agent teams for complex, dynamic multi-agent domains, with intended applications in arenas such as education, training, entertainment, information integration, and collective robotics. Unfortunately, uncertainties in these complex, dynamic domains obstruct coherent teamwork. In particular, team members often encounter di ering, incomplete, and possibly inconsistent views of their environment. Furthermore, team members can unexpectedly fail in ful lling responsibilities or discover unexpected opportunities. Highly exible coordination and communication is key in addressing such uncertainties. Simply tting individual agents with precomputed coordination plans will not do, for their in exibility can cause severe failures in teamwork, and their domain-speci city hinders reusability. Our central hypothesis is that the key to such exibility and reusability is providing agents with general models of teamwork. Agents exploit such models to autonomously reason about coordination and communication, providing requisite exibility. Furthermore, the models enable reuse across domains, both saving implementation e ort and enforcing consistency. This...

...Introduction 2.0 At present West Dorset standby rota consists of two areas and a 1- 5 call out system in each area. The area is split in two and each operator will have a number of sites to cover throughout his standby. 2.1 When on duty the standby operator will cover his area from 16.00hrs till 08.00hrs the following morning (week days) and 08.00hrs till 08.00hrs the following morning (weekends) during this period the operator could be called out should there be an alarm generated on one of his sites. The procedure for this is as follows: * Alarm generated i.e. fault or breakdown. * Alarm passed from control room to standby operator. * Standby operator attends site actions alarm. Depending on the alarm nature, the operator will decide on action to be taken. * Operator actions alarm contacts control to confirm alarm has cleared. * Once alarm is cleared operator returns home. 2.2 During this period the standby operator could be called out 1/2 times per night. Each operator would live with- in a 30 mile round trip to each site. With this method in place the operator can complete his call out in the shortest time possible and return home. 2.3 The operator’s 1-5 standby means each operator is required to cover his area once every four days this in turn adds to the following problems: * If the standby operator can’t cover his standby he must make sure his standby is covered by a member of his team. With only four members to ask, this...

...pointer. The normal syntax for announcing a pointer is type* variable_name; We can put the asterisk near to variable name, but it’s a good programming routine to put the asterisk close type because it shows that the pointer variable points to that kind of variable. For instance, we wish to announce a pointer that keeps the memory address of an integer variable. The announcement would appear as follows int* ptr; There are 2 operators linked with pointers. 1. Address-of operator(&) This operator is utilized to get the address of a variable. It's a unary operator. Let's see an illustration on the way to utilize this operator. int var = 9; //declare a variable of integer type int* ptr; //declare pointer ptr = &var; //assign the address of var to pointer variable 2. Indirection operator(*) This operator is utilized to access the contents of the address included in the pointer variable. Next to view the way we utilize this operator, we carry on from above illustration. Assume we wish to print the value in var utilizing ptr we can do this as follows...

...F1 , F2 , F3 > : R3 → R3 be a differentiable vector field. The divergence of F is the scalar function div F = and the curl of F is the vector field curl F = ∂F3 ∂F2 − ∂y ∂z i+ ∂F1 ∂F3 − ∂z ∂x j+ ∂F2 ∂F1 − ∂x ∂y k ∂F1 ∂F2 ∂F3 + + . ∂x ∂y ∂z Note that the divergence can be defined for any vector field F : Rn → Rn , while the curl is only defined on vector fields in 3-space. There is a nice second way to deal with these functions. Define the operator , called the “del” operator, by = ∂ ∂ ∂ i+ j+ k= ∂x ∂y ∂z ∂ ∂ ∂ , , ∂x ∂y ∂z The action of the del operator on a scalar function f : R3 → R is just the gradient: f= ∂f ∂f ∂f i+ j+ k= ∂x ∂y ∂z ∂f ∂f ∂f , , ∂x ∂y ∂z = grad(f ) The divergence and the curl of a vector field are given by the two vector products that we have: the curl is the dot product and the curl is the cross product. div(F) = ·F curl(F ) = × F. Theorem 1 Let f be a differentiable scalar function and F be a differentiable vector field on R3 . 1. curl(grad f ) = 0 or 2. div(curl F) = 0 or × ( f ) = 0. ·( × F) = 0. The Laplacian operator on a scalar function is defined to be f = div(grad f ) = 1 · f= 2 f. The Laplacian of a vector field F is F= F1 , F2 , F3 . Geometrically, the curl F is a measurment of the tendency of a fluid to swirl around an axis. A field F with curl F = 0 at a point P is called irrotational at P . The divergence of a vector field measures the incompressibility of a vector field and we can often interpret the divergence of a...
