Our Team

Introduction

• Just-in time delivery system

• Batch plants produce concrete

• Concrete strength must be constantly monitored

Testing Process

• Testing cylinders created

• Sent to testing laboratory

• Results analyzed

Analysis

C1a C1b T1 = (C1a + C1b)/2

--

C2a C2b T2 = (C2a + C2b)/2

--

C3a C3b T3 = (C3a + C3b)/2

R1=(T1+T2+T3)/3

… …CNb

CNb

TN = (CNa + CNb)/2

= 1/d (Rn)

• Two conditions must be met– R must not fall below the specified strength– No one test must be below specified

strength - 500

If either of these conditions are violated the concrete must be made stronger

Storyboard Model

Reports from the various testing labs come in on a daily basis depending on the size and number of jobs.

The main user, a secretarial position, will take the reports,

and using the CAP software enter the data.

Storyboard Model

When entering a new series of cylinder reports, we want to make sure the user is presented with an easy interface and also use a standard method to trap potential errors. We have devised a method called Echo Entry Kheck (EEK) that will echo the users entry so they can double check their input.

When a user just wants to view the progress and status of a job, no data entry is possible and a graph will be shown from the current available data.

Graphs

The user must have the ability to view three specific types of line graphs…

1. Plot of Averages

2. Plot of Standard Deviation

3. CUSUM Plot

Graphs

The user must be allowed to produce the averages plot and standard deviations plot based on different data sets.

1. All Values

2. Moving Average of Three Values

3. Moving Average of Thirty Values

4. Last 30 Values

The user will be able to choose from the following data sets for each of these graphs:

Graphs

The user will be able to produce CUSUM plots based on two data sets:

All Values and Last 30 Values

Important note: It will not be necessary to produce graphs showing multiple mixes. The graphs are only necessary to show the user data for individual mixes.
