Manufacturing Guide¶

Modeling Manufacturing¶

We want to record the batch manufacture of high specification items such as rotor blades by a contractor, which then inspects these individually and issues a certificate.

Manufacturing Items¶

Although various agents could be involved in the manufacturing activity, in this example, the contractor is the only agent responsible for the manufacturing of high specification rotor blades, which it does so in batches.

Item Manufactured

Modeling the Contractor Agent¶

The Contractor agent has two attributes, its CompanyName and its Location. In our Chronicle domain specification this is captured as follows -

attributes:
  CompanyName:
    type: String
  Location:
    type: String
agents:
  Contractor:
    attributes:
      - CompanyName
      - Location

Modeling the Item Entity¶

The Item entity has one attribute, its PartID.

attributes:
  PartID:
    type: String
entities:
  Item:
    attributes:
      - PartID

Modeling the ItemManufactured Activity¶

The ItemManufactured activity has one attribute, its BatchID. It also has a Manufacturer role.

attributes:
  BatchID:
    type: String
activities:
  ItemManufactured:
    attributes:
      - BatchID
roles:
  - Manufacturer

Certifying Items¶

Although various agents could be involved in the certification activity, in this example, the contractor is the only agent responsible for the certification of high specification rotor blades, which it does so individually. Therefore this activity uses the item and issues a certificate for it.

Item Manufactured

Modeling the Certificate Entity¶

The Certificate entity has one attribute, its CertID.

attributes:
  CertID:
    type: String
entities:
  Certificate:
    attributes:
      - CertID

Modeling the ItemCertified Activity¶

The ItemCertified activity has no attributes but it has a role Certifier.

activities:
  ItemCertified:
    attributes: []
roles:
  - Certifier

Chronicle Domain¶

Combining these fragments gives us our Chronicle manufacturing domain.

name: "manufacturing"
attributes:
  BatchID:
    type: String
  CertID:
    type: String
  CompanyName:
    type: String
  PartID:
    type: String
  Location:
    type: String
agents:
  Contractor:
    attributes:
      - Location
entities:
  Certificate:
    attributes:
      - CertID
  Item:
    attributes:
      - PartID
activities:
  ItemCertified:
    attributes: []
  ItemManufactured:
    attributes:
      - BatchID
roles:
  - Certifier
  - Manufacturer

Recording Manufacturing¶

In this example we will create a Contractor agent which will then embark on the following activities:

An ItemManufactured activity to manufacture a batch of rotor blades
A series of ItemCertified activities to certify each rotor blade in turn

Record Contractor¶

The first record is that there is a contractor called Helicopters PLC based in Bristol.

mutation {
  defineContractorAgent(externalId: "helicoptersplc", attributes:{
    companyNameAttribute: "Helicopters PLC",
    locationAttribute:"Bristol"}) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "defineContractorAgent": {
      "context": "chronicle:agent:helicoptersplc",
      "txId": "492c4827-d3c5-4427-8b43-d35f9ad58687"
    }
  }
}

Obtaining the list of Contractors¶

Note that you can always obtain the list of contractors known to Chronicle using this query -

query {
  agentsByType(agentType: ContractorAgent) {
    nodes {
      __typename
      ... on ContractorAgent {
        externalId
        companyNameAttribute
        locationAttribute
      }
    }
  }
}

The output should look something like this -

{
  "data": {
    "agentsByType": {
      "nodes": [
        {
          "__typename": "ContractorAgent",
          "externalId": "acmecorp",
          "companyNameAttribute": "ACME Corp",
          "locationAttribute": "Burbank, California"
        },
        {
          "__typename": "ContractorAgent",
          "externalId": "helicoptersplc",
          "companyNameAttribute": "Helicopters PLC",
          "locationAttribute": "Bristol"
        }
      ]
    }
  }
}

Manufacturing Rotor Blades¶

Record Manufacturing Activity Instance¶

mutation {
  defineItemManufacturedActivity(externalId: "rotorblade-manufacture-run-001", attributes:{ batchIDAttribute: "run-001" }) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "defineItemManufacturedActivity": {
      "context": "chronicle:activity:rotorblade%2Dmanufacture%2Drun%2D001",
      "txId": "93ad8dd6-4e97-45e0-9c60-ddb079863830"
    }
  }
}

Record Contractor's Role in the Manufacturing Activity¶

We assert that contractor was responsible for this activity in its role as a Manufacturer using the wasAssociatedWith relationship -

mutation {
    wasAssociatedWith(
    activity: { externalId: "rotorblade-manufacture-run-001" },
    responsible: { externalId: "helicoptersplc" },
    role: MANUFACTURER) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "wasAssociatedWith": {
      "context": "chronicle:agent:helicoptersplc",
      "txId": "59b26631-db0f-4c5d-a79d-9ff8d85564d4"
    }
  }
}

Record Start of Manufacturing Activity¶

mutation {
  startActivity(
    id: { externalId: "rotorblade-manufacture-run-001" }) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "startActivity": {
      "context": "chronicle:activity:rotorblade%2Dmanufacture%2Drun%2D001",
      "txId": "36d58122-35ec-4e66-a31b-1534710e310b"
    }
  }
}

Record the Manufacturing of Batch of Rotor Blades¶

For each rotor blade produced by this activity, we first record its creation.

NOTE that here we are focusing on a single rotor blade. However, in a real world example, this process would be repeated and we would need to make sure that the externalId and PartID were incremented.

mutation {
  defineItemEntity(externalId:"rotorblade-run-001-001",attributes:{partIDAttribute:"run-001-001"}) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "defineItemEntity": {
      "context": "chronicle:entity:rotorblade%2Drun%2D001%2D001",
      "txId": "630356af-01e1-42cd-9513-f52b59c70d53"
    }
  }
}

Then we assert that it wasGeneratedBy by the relevant manufacturing activity.

mutation {
  wasGeneratedBy(id: { externalId: "rotorblade-run-001-001" },
    activity: { externalId: "rotorblade-manufacture-run-001" }) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "wasGeneratedBy": {
      "context": "chronicle:entity:rotorblade%2Drun%2D001%2D001",
      "txId": "edde4708-e451-4bb6-b548-0cf818db5b3b"
    }
  }
}

NOTE that this is a bidirectional relationship and the fact that the manufacturing activity generated this rotor blade is inferred.

In this guide, we are only showing the recording of a single rotor blade, however, in practice, a batch will be associated with this activity, before the activity comes to an end.

Record End of Manufacturing Activity¶

mutation {
  endActivity(
    id:{ externalId: "rotorblade-manufacture-run-001" }) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "endActivity": {
      "context": "chronicle:activity:rotorblade%2Dmanufacture%2Drun%2D001",
      "txId": "51839346-b068-4946-9491-334d465faa56"
    }
  }
}

Certifying Rotor Blades¶

In this example, each rotor blade is certified, using a distinct activity.

Record Certification Activity Instance¶

Here, the identity of the activity can incorporate the PartID.

mutation {
  defineItemCertifiedActivity(externalId: "rotorblade-certify-run-001-001") {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "defineItemCertifiedActivity": {
      "context": "chronicle:activity:rotorblade%2Dcertify%2Drun%2D001%2D001",
      "txId": "e2ca580a-f0dd-4ea5-8bce-297a4f6800b7"
    }
  }
}

Record Contractor's Role in the Certification Activity¶

We assert that contractor was responsible for this activity in its role as a CERTIFIER using the wasAssociatedWith relationship -

mutation {
    wasAssociatedWith(
    activity: { externalId: "rotorblade-certify-run-001-001" },
    responsible: { externalId: "helicoptersplc" },
    role: CERTIFIER) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "wasAssociatedWith": {
      "context": "chronicle:agent:helicoptersplc",
      "txId": "e2998de6-1629-4924-aa90-b93b8ddd1c85"
    }
  }
}

Record Start of Certification Activity¶

mutation {
  startActivity(
    id: { externalId: "rotorblade-certify-run-001-001" }) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "startActivity": {
      "context": "chronicle:activity:rotorblade%2Dcertify%2Drun%2D001%2D001",
      "txId": "fc1570a7-1077-4839-9277-c906c834a8b4"
    }
  }
}

Record the Certification of a Rotor Blade¶

For each rotor blade certified by this activity, we first record its corresponding certificate generation along with its CertID. In this simplified example, the CertID of the rotor blade is the same as its PartID.

mutation {
  defineCertificateEntity(externalId: "rotorblade-certificate-run-001-001", attributes:{ certIDAttribute: "run-001-001" }) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "defineCertificateEntity": {
      "context": "chronicle:entity:rotorblade%2Dcertificate%2Drun%2D001%2D001",
      "txId": "2db682a4-c1cf-4ebd-8f07-8f81d6c9da2f"
    }
  }
}

Then, we assert that it wasGeneratedBy by the certification activity.

mutation {
  wasGeneratedBy(id: { externalId: "rotorblade-certificate-run-001-001" },
    activity: { externalId: "rotorblade-certify-run-001-001" }) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "wasGeneratedBy": {
      "context": "chronicle:entity:rotorblade%2Dcertificate%2Drun%2D001%2D001",
      "txId": "83acf7e3-afcc-4685-8f76-b34a91acff7f"
    }
  }
}

NOTE that this is a bidirectional relationship and the fact that the certification activity generated this certificate is inferred.

However, this time we also record the fact that the activity used the rotor blade.

mutation {
  used(id: { externalId: "rotorblade-run-001-001" },
    activity: { externalId: "rotorblade-certify-run-001-001" }) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "used": {
      "context": "chronicle:entity:rotorblade%2Drun%2D001%2D001",
      "txId": "d0eb8691-29e0-4264-aebb-31733f4ffb21"
    }
  }
}

Given the scope of this activity is limited to a single rotor blade, we now end the activity.

Record End of Certifying Activity¶

mutation {
  endActivity(
    id: { externalId: "rotorblade-certify-run-001-001" }) {
    context
    txId
  }
}

The output should look something like this -

{
  "data": {
    "endActivity": {
      "context": "chronicle:activity:rotorblade%2Dcertify%2Drun%2D001%2D001",
      "txId": "ae86576a-9e1f-4bef-9b74-c5c45c8b6ff7"
    }
  }
}

Querying Manufacturing¶

There are many queries that can be run. Here are a couple of examples.

Example 1¶

query {
  q1: entityById(id: { externalId: "rotorblade-run-001-001" }) {
    ... on ItemEntity {
      partIDAttribute
      wasGeneratedBy { ... on ItemManufacturedActivity { id } }
    }
  }
  q2: entityById(id: {externalId: "rotorblade-certificate-run-001-001"}) {
    ... on CertificateEntity {
      certIDAttribute
      wasGeneratedBy { ... on ItemCertifiedActivity { id } }
    }
  }
}

The output should look something like this -

{
  "data": {
    "q1": {
      "partIDAttribute": "run-001-001",
      "wasGeneratedBy": [
        {
          "id": "chronicle:activity:rotorblade%2Dmanufacture%2Drun%2D001"
        }
      ]
    },
    "q2": {
      "certIDAttribute": "run-001-001",
      "wasGeneratedBy": [
        {
          "id": "chronicle:activity:rotorblade%2Dcertify%2Drun%2D001%2D001"
        }
      ]
    }
  }
}

Example 2¶

query {
  activityTimeline(forEntity: [{ externalId: "rotorblade-run-001-001" }],
                  activityTypes: [],
                  forAgent:[]
                  ) {
      pageInfo {
          hasPreviousPage
          hasNextPage
          startCursor
          endCursor
      }
      edges {
          node {
              __typename
             ... on ItemCertifiedActivity {
                started
                ended
                wasAssociatedWith {
                  responsible {
                    role
                    agent {
                      __typename
                      ... on ContractorAgent {
                        companyNameAttribute
                      }
                    }
                  }
                }
              }
              ... on ItemManufacturedActivity {
                started
                ended
                wasAssociatedWith {
                  responsible {
                    role
                    agent {
                      __typename
                      ... on ContractorAgent {
                        companyNameAttribute
                      }
                    }
                  }
                }
              }
          }
          cursor
      }
  }
}

The output should look something like this -

            "wasAssociatedWith": [
              {
                "responsible": {

                  "agent": {
                    "__typename": "ContractorAgent",
                    "companyNameAttribute": "Helicopters PLC"
                  }
                }
              }
            ]
          },
          "cursor": "0"
        },
        {

            ]
          },
          "cursor": "1"
        }
      ]
    }
  }
}

Example 3¶

query {
  activityTimeline(forEntity: [{ externalId: "rotorblade-run-001-001" }],
                  activityTypes: [],
                  forAgent:[]
                  ) {
      pageInfo {
          hasPreviousPage
          hasNextPage
          startCursor
          endCursor
      }
      edges {
          node {
              __typename
             ... on ItemCertifiedActivity {
                started
                ended
                wasAssociatedWith {
                  responsible {
                    role
                    agent {
                      __typename
                      ... on ContractorAgent {
                        companyNameAttribute
                      }
                    }
                  }
                }
              }
          }
          cursor
      }
  }
}

The output should look something like this -

    "activityTimeline": {
      "pageInfo": {
        "hasPreviousPage": false,
        "hasNextPage": false,

          },
          "cursor": "1"
        }
      ]
    }
  }
}
