This article is based on a sample included in a presentation that I conducted a couple of months ago. Essentially, this example pulls utilization schedules from multiple equipment resources and generates both an equipment resource specific calendar and a graphical overview of the calendars for all equipment resources. This demonstration uses ADO with a direct connection to an Oracle database for both scheduling the work orders that need to be processed at each of the equipment resources (using a very weak scheduling algorithm that does not go back to fill in unused time), and to create the graphical results in Excel.
The options area for the original Excel spreadsheet used in my presentation looked like this, but we will not create anything that complex in this article: 
–
Before starting, we need to create source data for our example (note that some of the tables created are only needed for a short period of time, and may be dropped once all of the tables are created):
First, a statistic list of parts that will be manufactured:
CREATE TABLE
T_PART_LIST AS
SELECT
CAST(DBMS_RANDOM.STRING('U',15) AS VARCHAR2(30)) PART_ID,
ROUND(DBMS_RANDOM.VALUE(1,30)) NUM_LOTS,
ROUND(DBMS_RANDOM.VALUE(1,10)) NUM_OPERATIONS
FROM
DUAL
CONNECT BY
LEVEL<=100;
Next, the operation numbers and machine resources that will be used during the manufacture of each of the parts:
CREATE TABLE
T_PART_OPERATION AS
SELECT
PL.PART_ID,
OP.RN*10 OPERATION_SEQ_NO,
CAST(ROUND(DBMS_RANDOM.VALUE(0,10),2) AS NUMBER(22,2)) RUN_HOURS,
CAST('MACHINE'||TO_CHAR(ROUND(DBMS_RANDOM.VALUE(1,100)),'000') AS VARCHAR2(15)) RESOURCE_ID
FROM
T_PART_LIST PL,
(SELECT
ROWNUM RN
FROM
DUAL
CONNECT BY
LEVEL<=10) OP
WHERE
OP.RN<=PL.NUM_OPERATIONS;
CREATE INDEX IND_T_PART_OP_PART_ID ON T_PART_OPERATION(PART_ID);
Next, the work order lots that will manufacture the parts:
CREATE TABLE
T_WORKORDER_LIST AS
SELECT
WO.WORKORDER_BASE_ID,
CAST(LN.LOT_NUM AS VARCHAR2(3)) WORKORDER_LOT_ID,
PL.PART_ID,
TRUNC(SYSDATE+ROUND(DBMS_RANDOM.VALUE(0,400))) DESIRED_WANT_DATE
FROM
(SELECT
PART_ID,
NUM_LOTS,
ROWNUM RN
FROM
T_PART_LIST) PL,
(SELECT
CAST('W'||TO_CHAR(ROWNUM+10000) AS VARCHAR2(15)) WORKORDER_BASE_ID,
ROWNUM RN
FROM
DUAL
CONNECT BY
LEVEL<=400) WO,
(SELECT
ROWNUM LOT_NUM
FROM
DUAL
CONNECT BY
LEVEL<=30) LN
WHERE
PL.RN=WO.RN
AND LN.LOT_NUM<=PL.NUM_LOTS
ORDER BY
WO.WORKORDER_BASE_ID,
LN.LOT_NUM;
Finally, a table that will eventually contain the schedules for the various machine resources:
CREATE TABLE T_RESOURCE_DAILY_SCH( RESOURCE_ID VARCHAR2(15), START_DATE DATE, FINISH_DATE DATE, RUN_HOURS NUMBER, PART_ID VARCHAR2(30), WORKORDER_BASE_ID VARCHAR2(15), WORKORDER_LOT_ID VARCHAR2(3), OPERATION_SEQ_NO NUMBER, DESIRED_WANT_DATE DATE, UNIT_ASSIGNED NUMBER); CREATE INDEX IND_T_RESOURCE_DAILY_RES ON T_RESOURCE_DAILY_SCH(RESOURCE_ID);
We now switch to Excel to build the interface area with two ActiveX command buttons:
First, name the first worksheet as ShopCalendar – this name is very important since it is referenced in the code for this example. Next, add two ActiveX command buttons in the first two rows. Give the first one the name cmdCreateSchedule, and the second one the name cmdDrawCalendar – the names are not overly critical, but the names are referenced in the code. Finally, double-click one of the buttons to access the Code Editor.
Delete any code that is shown in the Code Editor and add the following code:
Option Explicit
Dim dbDatabase As New ADODB.Connection
Dim strDatabase As String
Dim strUserName As String
Dim strPassword As String
Private Function ConnectDatabase() As Integer
Dim intResult As Integer
On Error Resume Next
If dbDatabase.State <> 1 Then
'Connection to the database if closed
strDatabase = "MyDB"
strUserName = "MyUser"
strPassword = "MyPassword"
'Connect to the database
'Oracle connection string
dbDatabase.ConnectionString = "Provider=OraOLEDB.Oracle;Data Source=" & strDatabase & ";User ID=" & strUserName & ";Password=" & strPassword & ";ChunkSize=1000;FetchSize=100;"
dbDatabase.ConnectionTimeout = 40
dbDatabase.CursorLocation = adUseClient
dbDatabase.Open
If (dbDatabase.State <> 1) Or (Err <> 0) Then
intResult = MsgBox("Could not connect to the database. Check your user name and password." & vbCrLf & Error(Err), 16, "Excel Demo")
ConnectDatabase = False
Else
ConnectDatabase = True
End If
Else
ConnectDatabase = True
End If
End Function
The above code is the basic logic needed to permit connecting to the Oracle database. Next, add a reference to the ActiveX Data Objects. Now we need to add the code for the scheduling routine – this code uses bind variables to minimize the number of hard parses:
Private Sub cmdCreateSchedule_Click()
Dim intResult As Integer
Dim strSQL As String
Dim i As Integer
Dim intResourceIndex As Integer 'Index that indicates the current resource ID index
Dim strResourceID(100) As String 'Keep track of the new resource IDs read in
Dim varResourceLastDate(100) As Date 'Keep track of the last date for the resource
Dim strWorkOrderLast As String 'Used to make certain that the next operation starts after the previous
Dim varWorkOrderLastDate As Date 'Used to make certain that the next operation starts after the previous
Dim varScheduleStart As Date 'The first date in the schedule
Dim snpData As ADODB.Recordset
Dim comData As ADODB.Command
intResult = ConnectDatabase
If intResult = False Then
Exit Sub
End If

Flavio,
If you have a copy of Microsoft Excel, even the 2016 version, you should be able to very quickly create the sample Excel files by following the directions in this article. All of the necessary code is included in the article. I originally created this example for a presentation that I gave to a Visual Manufacturing user group in June 2009. If you are a member of the VMIUG-TEC Yahoo group, you can access the full set of sample files and my presentation from that group’s file area.
Hi, Mr. Charles Hooper,
